If I get 140 in pcm and 62% in HSC so can I get admission in engineering colleges?
As per your query you need to know that in most of the engineering colleges the minimum eligibility criteria is: Candidates are required to have passed 10+2 from any recognised Board in India with a minimum of 50 percent marks in PCM.
Minimum marks required by SC/ST/OBC candidates is 45 percent.
So if you belongs to reserved category then I think you can get admission .Otherwise for general category it seems impossible as in PCM you got 140 marks out of 300 which means 46% only.
Hope it helps , thank you.

Definitely you'll get admission
But after completion of BE , This might be a hurdle for you..
Yeah but anyway try to increase that percentage in engineering..so that your resume may get good impression during any interviews
Hope you got the right information
Thank you

Yeah there is chance of getting in good colleges when you have the percentage of 55 plus in PU i.e 12th where you have and quite average score in 10th as well , i would also like to say with your score its hard to get top or good colleges without donation. So without donation you will get average college which accept plus 12th score

Yes! But it depends on whether you are from state board or central board. Some college have less cutoff for CBSE students. Some private universities have cutoff as 60 for PCM and overall 60% provided you have already got a good rank in their entrance exam. Moreover jee rank matters allot.
Thankyou
