Where do students usually start preparing for CUET, CLAT, and IPMAT ?

I’ve been noticing a lot of discussion around competitive exams like CUET, CLAT, and IPMAT — each one testing very different skills. CUET: subject knowledge + aptitude CLAT: logical reasoning, reading, legal aptitude IPMAT: mix of quantitative aptitude and verbal ability For anyone who has prepared or is currently preparing: Which exam did you find toughest? Did you rely more on coaching centers, self-study, online resources, or mock test platforms? If someone is just starting out, where should they begin preparation for these exams? Books, test series, or a structured study plan? Would love to hear different perspectives especially tips from those who’ve cleared or are currently working towards these exams.
