i'll get 70% in 12th standard and AIEEE rank will be beyond 2 lakh.. how should i get a gud college anywhere in india?

With this rank you will not have the option to select from very many. The best option for you would be to get into the college which is coming your way and excel in your engineering studies thereafter and aim for a reputed college for higher education after B.Tech / B.E.

if yr Aieee rank is beyond 2 lakh then you Cant get any good college or university in india.......however u can go for State universities common entrance test like IP university CET or Maharashta CET e.t.c..............may be u get some good college after clearing these state universities CETs......
