If you have good Intermediate score, and you still remember concepts, so that mere revision is enough to recollect them, then yes it is easy to get under 10,000.
All you need to do is divide the time into 2 halves, one half for preparation and the other half to solve mock question papers and previous papers.
1. Don't study too much - if you do this, consider you are gone?
2. Practice solving question papers within 3 hours - this will fetch you good rank. Trust me, for EAMCET, all you need is paper solving capability more than concepts. (Ask anyone who wrote EAMCET, they will say the same) (I choked in exam, because I didn't manage time well.)
That doesn't mean you don't study at all, Just practice tests more than studying. First solve some papers so that you will get an idea of what topics are being asked compulsorily in every paper, don't lose the compulsory question. Paper solving Strategy (followed by EAMCET 2013, GATE 2011 toppers): Skim the question paper quickly to answer one liner questions, direct questions. Postpone big questions and calculation involved questions. Once you answer the first batch questions in all subjects you will get some confidence. Next is answering some thought, calculation involved questions, Postpone questions which you are unable to solve, after you answer second batch you can already get a rank under 10,000. If you have any more time solve the big and unanswerable questions. You got to be swift all along. You got to work very hard for this one month if you forgot topics.
