Hello. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I do not understand what you mean by material synopsis. Is it from some coaching institute? It would be better if you could clarify a bit.

Anyways, JEE Mains syllabus is based purely on the NCERT / CBSE topics of class 11 and 12.

I would first advice you to study the books thoroughly before carrying out further preparation. Right now, you should be in a state where you have done at least one revision of all topics in all subjects and should have done at least 2 or 3 mock test papers. 

I would also advice you to look at the past year question papers of JEE Mains by Arihant. The tips given in the book will be very useful during the actual exam paper. 

Hope this helps you and all the best!
