Hello sir I am Palaniappan from grade 8 Rama 9 I need advise on getting good marks on the unit tests assigned to me in Askiitians. I spend so much time on studying for both maths and science exams, atleast 19 hours a day and I do a lot of hardwork, but i am still not able to get good marks sometimes i dont even get half the marks. When I give this much input on studying for these exams I also expect the same amount of output which I am not able to achieve. Please give me some advise on how to score good marks and also what book to use for askiitians, and also how do we answer questions that are not in the syllabus, because in that part I struggle alot.
