I have completed 11 just now...When should I apply for top private universities for engineering or anything
For most of the Private colleges eligibility criteria for engineering is to Pass with 60% aggregate marks in 10+2 with PCM and for other courses it is around 50%.
Though most of them have management quotas, they also highly consider JEE main marks for engineering.
So for now, you should concentrate and prepare for your 12th boards.
all the best :)
