thanks for asking your query ,as per kcet exam point of view you should not ship any chapters because surety cannot be taken that alots of questions will come from a particular chapters therefore to gain more and more marks focus on each and every chapters
Every chapter is important for a exam as per the prescribed syllabus. No one can know from which chapter mostly questions are asking. the previous trends may change this year. For better preparation solve previous year question papers too along with regular chapter study. Covering most of the topics and having a clear cutoff concept is good for cracking a exam.
Hope it helps!
