i didn't start my eamcet preparation what should i do to get atleast 75 marks

Hello,

With very limited time left,what you need to do is practice more and more questions from the topic that carry more wastage. You must also solve previous 5 year question papers in order to get good marks. Leave those topics that you find difficult because that will consume more time and the input/output ratio will be very less. Read less revise more, and more solve questions as many as possible.

I hope this helps.
