Dear aspirant! Ap peamcet i.e. andha pradesh  engineering  ,agriculture,  Medical common entrance test . 

Which is conducted  by  andhra pradesh state council of higher education.

This carries 160 as full mark out of which 25%  is the qualifying  marks i.e.40 marks .

50000 is very low rank to get college  in kurnoor . 

50000 can be estimated  as 40 - 50 marks. Im sorry to say  this very  low  to get any good or top college. But you try for the private  one . 

In private  colleges  there is quite little chances  to get cse .

Thankyou  ! And all the best
