Can I get admission in any Engineering college if my overall percentage is 80% but I scored 70 in Maths, 75 in Physics and 79 in Chemistry?
In best of my knowledge, you will be able to get admission in most of the engineering colleges as most of them have the criteria regarding the overall percentage in PCM that is 75% in most of the cases.
But if any college has any criteria regarding the individual percentage of any subject then in case of maths you won't be able to make it as your marks in maths are quite low for an Engineering student.
I would suggest you get clear knowledge about the eligibility criteria for any college you will apply in future else your ignorance can definitely bring you trouble.
Hope you will be able to find a good college for yourself. Best of Luck.
