I am in First puc right now. I am aiming for a rank below 500 in kcet exam. Should i prepare particularly for kcet only in my second pu or should i go directly with the preparation of JEE because some peope say that preparing for JEE will also help me fetch a good rank in kcet.

Hello,

If you will prepare for JEE whole heartedly then KCET will be very easy for you. Although KCET has different question pattern and are mostly similar to PUC syllabus but questions in JEE are way more advanced then KCET. So, in my opinion you should prepare seriously for JEE and beside solve questions from your PUC books too in free time and that will suffice.

I hope this helps.
