  • Mr Oosthuizen has been a massive help for me as his one-on-one teaching caters to your personal weaknesses in the subjects of Maths and Science. His teaching style makes the subjects comprehensive and easier for content to fit together in your brain, like a jigsaw puzzle, which was a game changer for my learning. He made our lessons enjoyable and really fun to work through. His patience and insider tips and tricks for studying/answering exam questions were a standout to me, and helped me to improve my marks incredibly over the past two years of working through the subjects with him, even when I felt like dropping them. Mr Oosthuizen is someone I would recommend to anyone who needs individual attention and wants to see a steady improvement in their journey through Maths and Science. He helped me to enjoy the subjects so much better. It is a definite 10/10 from me. Govind S (2024, Gr. 12)


  • Mr. Oosthuizen is an exceptional tutor who truly went above and beyond to ensure my success. He tutored me Physical Sciences in my Grade 12 year. I had lost my confidence and had a block against Chemistry. I've gained not only better marks but Mr. Oosthuizen helped me overcome my block and helped me regain my confidence. Mr. Oosthuizen is patient and explained topics to me over and over until I understood the topic. Thanks to Mr. Oosthuizen, I started to enjoy Physical Sciences and the complex topics suddenly didn't feel so complex. I highly recommend Mr. Oosthuizen to anyone who is looking to excel. Ninke S (2024, Gr. 12)

  • I had Physical Sciences and Maths tutoring for 2 years. The benefits are an increase in marks and better understanding of the content. The tutoring reduced my stress levels and gave me confidence I thought I never had. The experience was amazing and Mr Oosthuizen is a great tutor that understood my struggle and helped me overcome it. I would most certainly recommend. Tristan G (2023-24, Gr. 11,12)

  • Meneer Oosthuizen is meer as net 'n onderwyser. Hy is iemand wat tyd maak vir klas enige tyd van die dag. Hy is iemand wat moeilike konsepte vereenvoudig. Meneer Oosthuizen gee om vir sy leerders en stel werklik belang in wie hulle is en is altyd bereid om raad te gee of te help. Hy help jou om jou doelwitte te gebruik. Marli D (2021-23, Gr. 10-12 Wiskunde en Skeinat)


  • Mr Oosthuizen has been my tutor for almost 2 years and has helped me get an A for Science. He takes the time to explain the logic he uses to reach an answer and doesn’t mind going back to the basics to help you grasp a concept. My weekly lesson with him gave me the confidence to tackle difficult questions on my own and even grow to enjoy certain topics of Science. I have enjoyed my time with Mr Oosthuizen and am grateful for the opportunity to learn from him. Alex N (2021/22, Gr. 11, 12)


  • Mnr. Oosthuizen se klasse het my verskriklik baie gehelp. Ek sou, sonder geen twyfel, nie deur die jare kon kom sonder meneer nie. My punte het beslis verbeter; selfs tot 'n vlak waar ek dit nie kon glo nie. Meneer was altyd 'nice' en aangenaam, en ook 'flexible', en altyd lekker om mee te praat . Die een-tot-een klasse help beslis, en is vir my baie beter as ekstra lesse in 'n groep . Die tye wat ook kon verander soos dit my pas, en meneer wat altyd bereid was om klas te gee selfs al het meneer iets anders aan. Baie dankie vir alles meneer. LD v Z (2020/21, Gr. 12)

  • Being tutored by Mr Oosthuizen throughout my matric year was a wonderful experience. With his help in Physics I gained so much more knowledge and understanding on the subject that I had previously been struggling with. The use of Zoom for lessons was much appreciated, because it was convenient and safe, considering the spread of the Corona Virus. Mr Oosthuizen's use of technology and practical examples made the work being taught much more understandable. With the help of Mr Oosthuizen in Physical Sciences I was able to increase my marks by about 15% and for that I am truly grateful. Unam K, (2021, Gr. 12)

  • I used my pocket money to pay for the Alex science workshop and it was great use of money. The classes where extremely educational and suitable for most learning styles as sir often used demonstrations to explain a concept and handed out notes. The only criticism one might have is that the classes are long but we take breaks in between to give the brain a break and allow oneself to concentrate again. Palesa M (Aug. 2019 Workshop, Gr. 12)

  •  I found the workshop very helpful. It provided us with a lot more focus on smaller yet equally important concepts in Physical Sciences. I personally feel like the manner in which subjects were handled during the workshop were more innovative and clear. Furthermore the material used to explain the handled matters were also a bonus because we could literally see how everything happens. I am very happy about the workshop because in space of 4 classes of 2 hours each, of which I unfortunately could only attend half of, I learnt a lot more than I expected. Thank you, Sir. Liyema N (Aug. 2019 Workshop, Gr. 12)

  • I enjoyed it very much, we worked on exam content and covered a lot of work during these four lessons. Three hours per session are long, but Mr Oosthuizen made a good attempt to make the time go faster in an enjoyable way. It was very helpful and the contents that we covered, helped a lot in the preparation for the exams. It was a nice way to recap the work you have forgotten, and get some practice in the important topics. I would highly recommend this workshop to anyone else. Contasha V (May 2019 Workshop, Gr. 12)


  • Thank you so much for your time and effort put into this workshop! Was definitely worth sacrificing hours of my Friday’s. This was very beneficial, as it summarized and went through all chapters which needed to be covered for exams in a friendly environment, and this makes me feel a lot more prepared and takes stress off my shoulders! I would DEFINITELY do more classes and would love to join in the August ones. Thank you so much sir. Nikole A (May 2019 Workshop, Gr. 12)


  • Ek waardeer alles wat Meneer vir ons geleer het. Ek het voorheen gesukkel om die werk te verstaan, maar na al die klasse wat ek bygewoon het, het dit alles net beter gegaan, en ek is baie positief oor die komende eksamen........meneer se metodes was baie makliker om mee te werk......ek sal weer by die volgende werkswinkel wees, definitief!!  Shelton P (Mei 2019 Werkswinkel, Gr. 12)

  • I just wanted to say a big thank you for deciding to host the June preparation workshop for grade 12 Physical Sciences 2019. Revising through the term one work again, really helped me prepare for what is to come in June exam. All the work that might have been forgotten has definitely been remembered and enriched with new and better ways of answering. I was really glad that we stuck to the examination guidelines and that we answered past paper questions so that we know what sort of questions are repeated and are specifically difficult. The short summaries that you included at the start of each booklet includes all the necessary information and really simplifies the work in the best way possible. You were patient with us all and explained the work so that we can all understand and work through the questions feeling good about our answers. All in all I am really grateful for the workshop and I will definitely recommend it to others. I will be back in August.  Mieke D (May 2019 Workshop, Gr. 12)


  • Die ekstra klasse het my baie gehelp en ek voel nou meer positief oor die Junie eksamen. Die klasse was uitstekend!
    Weereens, dankie vir Meneer se moeite. Ek waardeer dit hartlik. Ruben S (Mei 2019 Werkswinkel, Gr. 12)


  • Attending extra lessons with Mr Oosthuizen is one of the best decisions I have made for my high school career.   Choosing Mr Oosthuizen as tutor was not a difficult decision for me as he had assisted my two elder sisters in achieving highly impressive marks in Physical Sciences which paved the way to their tertiary education.

    During extra Science lessons Mr Oosthuizen provides his students with challenges to prepare them for tests and exams.  He embraces all questions and encourages complete understanding; to improve understanding he even uses scientific equipment.  I have never left an extra lesson not feeling more confident on section than I did before.  The lessons allowed me to look at sections from different perspectives. The group lessons exposed me to different ways of thinking.

    Mr Oosthuizen’s intense passion for his job is most definitely reflected in his way of teaching as well as by how he interacts with his students. Siviwe Q (2018, Gr. 12)

  • I really enjoyed the workshop and found it super helpful. Going through past papers and doing the important theory worked really well! The booklet was very organized and well done.
    Getting a treat and a break in between was definitely good, because the class was quite long. I really enjoyed it though. It was a really good experience and revision for my June exam.
    I will definitely do it again! Mia J (May 2018 Workshop, Gr. 12)

  • The tutoring experience was very positive for me. The explanations are very detailed and cover all aspects of the topics very well. Doing exam and test questions at tutoring help when answering questions in tests and exams. Ebet B (2018, Gr. 10)

  • Before I started extra science lessons, I hated the thought of science. Mr Oosthuizen gave me a completely new view point on the subject and over the past two years I have actually been able to start enjoying the subject! I’ve been able to raise my marks and maintain an A for science.  Nikhil R (2018, Gr. 12)


  • The workshops are the best way to prepare for your final exams. The interactive style of his teaching is truly engaging and will encouraged me to really  get a grip on the work. We covered plenty of old papers and he would explain to us how to correctly answer the questions in order to get the most marks. I would strongly encourage anybody to attend the workshops.  Adriaan B (2018, Gr. 12)


  • I came to Mr Oosthuizen for about 5 months. I attended Mathematics and Physical Sciences classes. The classes and workshops were all very informative and they helped me a lot. Mr Oosthuizen is very professional in all of his classes and each and every lesson and workshop was very effective. I highly recommend that you attend Mr Oosthuizen's lessons and workshops if you require any assistance in these subjects  Kristen S (2017, Gr. 12)


  • I have attended extra Maths classes with Mr Oosthuizen for a year. He helped me to increase my expectations for my abilities in Maths. The classes were always presented in a relaxed environment, and were effective as I remember starting at a very low mark in Maths and my marks improved! Mr Oosthuizen had a lot of patience and his personality made the classes fun and pleasant to go to.  Cailin G (2017, Gr. 12)

  • I've attended Mr Oosthuizen's lessons for about a year and a half where he helped me with Physical Science and even a bit of Afrikaans here and there. I always brought my questions that I needed help with and he always answered them and even explained further. I don't think I would have gotten through all the Chemistry without him, as I really struggled with Chemistry this year, and Mr Oosthuizen helped me understand and I managed to get through the final exam. He was always very helpful and I enjoyed going to his lessons.  Robyn P (2017, Gr. 12)

  • Although I only attended for a short while I benefitted and learn a lot from the classes and workshop I attended. I felt more confident and ready for my exams and I enjoyed the relaxed and fun environment of the lessons. It was clear that you always had our best interests at heart and did everything you could to make sure we understand. Thanks for everything!  Emmilia K (2017, Gr. 12)

  • I went to mr O for 2 years for Science tutoring and 1 year for Maths tutoring. In those 2 years, my confidence in both Maths and Science increased incredibly because Mr O made me feel like I was capable of achieving way better marks than I was getting, which I thought was impossible. His tutoring classes helped a lot because he explained the work done in class a lot more thoroughly and teaches you the background to each section in order to help you understand better. Mr O is extremely professional and effective, he is never late and always takes lessons seriously- but not too serious that a joke can’t be made every now and then. Classes were always made fun and interesting and I feel like I would never have survived Maths or Science without his help. And the 3rd term workshop was also a worthwhile experience; it helped me a lot with understanding the work.  Jenna T (2017, Gr. 12)

  • The workshop helped me to get a greater understanding of the work that we covered in the term.  Luke P (2017, Gr. 12) 

  • Often you find that there is not enough time in class to ask questions or query a section you don't understand. Well in these extra lessons you can accomplish a lot and ask any questions you have, and leave understanding a section better. He explains topics in detail in order for you to be well informed and have a clear understanding. These lessons also help you prepare for external exams like the NSC exams. You go through previous papers with him and he shows you how to answer questions efficiently without babbling on or wasting time. I recommend attending his extra science lessons for those who want to improve and excel in their Science marks.  Mbali T (2016, Gr. 12)

  • I struggled a lot with Science at the beginning of the year and now Science is my favourite subject. Class is very structured and has a calm atmosphere. The Science classes helped me to achieve my goals and increase my marks with over 10%. The amount of time sir put in helped me to do better but also made me confident in the  work I had to learn. These classes changed my outlook on Science and now I want to incorporate Science in my career in the near future.  Elz-Mari D (2016, Gr. 10)

  • I have had the privilege of being taught by Mr Oosthuizen. Not only was the experience professional, but it was an enjoyable one as well. He was able to simplify my school work. Topics that use to be difficult was now more understandable. My marks increased soon after taking classes with him. He is a man of Science; I highly recommend him to all Science students.  Joshua G (2016, Gr. 12)

  • Mr O was my saving grace. I am so sorry that I did not go to him from the start of grade 10. I only heard about him at the end of grade 11. He explains the work in such a way that you cannot wait for the next lesson. He also did experiments with me that we never got to do at school. We worked through past papers and the way he interacted with me during extra classes kept me on my toes. No time to day dream.  Nicola M (2015, Gr. 12)

  • I attended extra Science classes with Mr Oosthuizen on a Thursday evening, it was an hour lesson focused on what I struggled with in Science, either related or not related to what we were busy with in class. We worked through problems and were encouraged to think and solve them without help before seeing the answer. We organized extra tutor sessions the night before tests and exams to help with questions and problems. The extra lessons helped with my general understanding of Science;  I reached my goal mark at the end of Matric and it helped me in first year Chemistry as I'm studying B.Sc Biochemistry.   Emma S (2015, Gr. 12)

  • Mr Oosthuizen is a great educator, his ability to connect with me as a student helped me immensely in understanding difficult concepts. During my lessons with him, he was willing to put in a lot of extra time and effort to ensure I could cope with the work.
    I would recommend him to any student seeking help with their academics, as his lessons are truly worthwhile.  Reinhardt F (2014, Gr. 12)

  • Science is undoubtedly one of the most daunting school subjects, but Mr Oosthuizen's lessons made it enjoyable and interesting. He never treated a question as though it was without merit, and he was always willing to explain something more than once, in different ways, until he was certain his students were comfortable with the concepts. His lessons helped not only in getting to grips with the syllabus content, but also in preparing for exam questions and in imparting study techniques that have continued to be useful throughout university. He is a brilliant, approachable tutor and a warm person who cares about his students and their goals. I could not recommend his extra lessons enough for anyone taking Science.  Lauren K (2011, Gr. 12)
