I am like to finish my JEE syllabus to a very good level by mid of december:is it okay or have to do it by nov. end by leaving minor topics.

I am very confident that I will do every topic excellent way but it would take me top mid december. Though I will start giving test series by 1 december_ but I have heard that we should finish it by november end. So should I wrap up by november end by leaving minor topics? Please HELP.
