May God bless Khan Academy for having such huge influence on millions of Indian students. I am in class 11th and I was able to complete 12 chapters of math from Khan Academy in 11 days. The content is amazing and the intuitive learning is life changing. And since you guys are like family, we expect more from you. IIT JEE is the one of the toughest exams, in the world. Thousands of students start preparing for it from 6th grade, 9th grade or 11th Grade. But the coaching institutes that prepare students for this exam are highly expensive. Students have to spend half a million to 1 million rupees for two year coaching and yet many students are not able to clear the exam. That might be because of the rote learning approach. If Khan Academy makes JEE Prep course, then it would be one of the biggest impact in the world. Sal Khan is an amazing teacher and the Khan Academy India team is extremely awesome too. I believe your preparation course will be better than most of the coaching institutes. Now I shall come straight to what you should make. 1. The first step in JEE preparation is clearing concepts. Since, you've already made subject wise courses upto Class 12. That's great. But you have to add some more concepts of JEE Advanced level. Also, every Indian might not understand Sal's American accent (though many would, plz don't remove it, I like learning from Sal). What you can do is dubb your videos is hindi ( for Hindi speaking students) and in Indian English accent (for Indians who don't speak Hindi). You can provide an option in the videos to change audio language. 2. Once you are done with the JEE syllabus, the next step is to practice high level questions and increase speed and accuracy. This part must be easy for Khan Academy, as there are literally thousands of quality questions available everywhere, and in books like Irodov, HC Verma, Problems Plus, etc. You can take questions from there and provide them as articles and practices or something new, if you wanna be creative. But do provide sufficient solved questions videos so that the students understand how the questions are solved. 3. The next step is mock tests. Again you will find enough resources for making these. You can also provide All India live mock tests, so that students can get a sense of competition and improve on their potential ranks. 4. The last thing (maybe) is strategy videos which, though are sufficiently available on YouTube, you can provide them in one place or atleast you can provide links to channels and videos. Some good channels are, AcadBoost by Kalpit Veerwal (who got Rank 1 in JEE 2017), Vedantu JEE, Byjus's JEE, Anup Gupta, UnAcademy JEE, etc. I hope to hear from you soon. Plz make this soon. I have two years left for the test. 😂
