i have just gone to class 11 this April , i want to give JEE so i have also joined a coaching institute. now my coaching institute is super fast and i am not at all able to keep pace with chemistry as well as some part of physics(i am also not enjoying while studying them specially chemistry )even though i am loving maths there . due to this i am not able to build my concepts properly. now even i don't want to change my batch in my coaching as it has the best faculty and also since i am not clear with my previous concepts i am not able to cope up with the new topics that are taught now . i want to crack JEE and exams such as KVPY and RMO but if this continues i am sure i wont be able to crack them .i am thinking if i could study physics and chemistry in my school or on my own and would go for maths to the same coaching. would this be beneficial ?? also if i want to get into foreign colleges like MIT (Massachusetts Institute of Technology) what is required? is it better than IIT . also i have my interest in mathematics and want to do engineering what shall i do???
