Hi Sam, even I am from ap. Your 10th marks will have nothing to do with this. Your intermediate marks look absolutely fine. To qualify the AP EAMCET 2019, minimum 25% out of 160 marks will be required.

It means that you will need 40 marks and you have 42 hence you will go through but for a good seat check out the shortlistings of different colleges.

Hi aspirant

You can calculate your estimated rank by formula. Your( EAMCET marks)75%+( your intermediate marks) 25%. You can get your estimated EAMCET score. 

Minimum qualifying mark for EAMCET  is 40,as you get 42 marks you are qualified and your rank is in lakhs. Based on your score shortlist all the college that you want to apply..  

I hope this is helpful!!  Thank you
