Whether you find Maths in ISC easy or tough depends entirely on you. But, mathematics at this level is quite challenging. It is advisable not to take it lightly. You must realize that the level of hardness in class 10 and class 11 maths is different. In class 11, the hardness level increases dramatically. Only if you have a strong foundation, you can excel.

The most vital thing that you must keep in mind is that mathematics is not a subject which you can just memorize and an ace. You must understand the topic and build a strong foundation before you proceed to solve the problems in a specific chapter.

Also, remember that you must solve the regularly. If you do it repeatedly, then your brain will be able to retain the information easily. Moreover, if you have any doubts, do not suppress it. Make sure that you get it clarified by the teacher the very next day.
