Taking this course helped me to understand the type of content I should be expecting when I do computer science. In addition, the course provided me with documents that would be helpful as I start the subject.

By Troy Maalouf on 12/8/2024

Thorough preparation as well as notes to remember. Properly guiding through the entire process and each specific Criterion. Incredible insight for the IA.

By Marcus on 5/23/2024

This guy is simple reading out the marking scheme. No use. Don't buy.

By Noor Shehab on 3/26/2024

This course is saving me in IB. The explanations are very clear and accurate. If I follow it, a 7 is ensured soon. Mr John's delivery is also very engaging so I don't get bored when I watch!

By Saeed Chahine on 3/25/2024

This course is extremely helpful, especially for the IA. I was able to perfect my criterions and make the most out of my complex code. I got a 7 predicted from my teacher. Thank you!

By Sara on 3/23/2024

This helped me a lot with my IA and made it easier for me to work on it since it covered everything that had to be done. It also helped me with paper 2, because it's not my strong suit.

By Marzouk Hajaij on 3/21/2024

The course really helped guide me through the IA! I was confused as to which direction I should head in but now I've received a 7/7 predicted. Really helpful!

By Ryan Rached on 3/20/2024

Life changing! Prior to watching the course I was completely clueless about how to do the IA well and struggled to grapple the IB CS course. Now I feel like I can achieve great success in my IA and a high score on my IB CS official.

By Freddy on 3/9/2024

Amazing course. Got a 7/7 predicted after watching these detailed videos and implementing every single tip from the course. Thank you!

I have taught IB CS off and on, as well as numerous other computer science courses, for over 4 decades. I’ve taught in the US, South Korea and at two international schools in East Africa. From my experience, students with US and East Asian backgrounds really struggle with the level of ambiguity presented in IB CS exams (in comparison to AP exams for example). I found it challenging to help students develop the skills required on the written tasks. Mr. Iglar provides numerous examples of how to approach these problems. Additionally, the topics covered will surely give additional content knowledge. If I were teaching IB CS in the classroom I would do my best to have students sign up at the beginning of year 1. Mr. Iglar’s Section 2 provides great insight into how to approach a course like IB CS. Furthermore, these points are rarely covered by teachers in our quest to cover the extensive content of the curricula. I would then set goals for students to finish Mr. Iglar’s Udemy course before my end of year 1 exam. The fact that students wouldn’t have covered some concepts is not as important as the methodology that Mr. Iglar is going through. Another good option would be to complete the relatively easy first and second section during the first couple of weeks of the first year, then save the rest for the break between year one and two. At that point you’re likely to know more of your weaknesses when it comes to IB CS questions. Like every learning experience, you’ll get out of it what you put into it. Those that allocate the appropriate amount of time and energy to attempt the problems on their own, as designed by the course, will of course gain the most. Because, we can’t learn without making mistakes, said some CS Sensei somewhere.
