Dear Pratap,

If something is not included in your school syllabus, you can purchase a suitable book on the topic(there are plenty of them catering to IITJEE),and learn through self-study.

Coming to your second question, FIITJEE has its own version of the NTSE exam, in which those who perform well in their exam are awarded scholarships irrespective of whether or not they join a FIITJEE course. 

Please feel free to post as many doubts on our discussion forum as you can. If you find any question
Difficult to understand - post it here and we will get you the answer and detailed solution very quickly. We
are all IITians and here to help you in your IIT JEE preparation.

All the best Pratap !!!
