Dear Mr. Satish;

this is not necessary that question will come from these chapter. this is not given in any entrance that particule number  of question will come in enrance. these chapter are not linked with other chapter so if you will skip these chapter , hardely you will lose 1 or 2 question in JEE. Yes, these are not important chapter.
