Hello,

Hope you are doing well!

So for EAMCET, there is no minimum marks required. If you have passed your 12th from a recognized board, you can apply for EAMCET.

But for JEE Mains, you are not eligible as the minimum marks must be 75% or more in your 12th class with PCM. (65% for SC/ST)

You can check eligibility criteria for both in detail here,

Hope this will help.
