I would appreciate if you could add a feature that helps IGCSE students study for their external exams in grade 10. I am currently in Grade 9, and have been taking the course for 10 weeks now. Your videos help me but I feel that they are more inclined towards the SAT course. Some specific videos targeted towards IGCSE students such as me. I have faced a challenge of studying biology since I am not so good at it.
I hope that you take these points to heart and help out the many IGCSE students that visit your website daily in search of help. This would truly make your website the best
