is it good to change to a cbse school if you are in an icse after 10th for iit preparation?my friends are prefering this .

hello respected ma'am, i have just passed from 10th class with 91%(icse).i am worried about my next class as my classmates are changing their schools.my friends have gone to a school -combined-coaching in which iit coaching will be given with normal studies.but i dont think its a good plan .
