I hav scored 46.33%in pcm in hsc board are there any chances of getting admission in engineering colgs?

Well the good thing now is there are tons of engg colleges out there, i'm sure you can find one that would take you in. Although don't bet you can get into the best college, coz with that kind of percentage it's difficult. But a lot also depends upon your score in AIEEE and other such entrance examinations.. Best of luck
