Hi

It depends from college to college. Usually cutoff for science will be higher than commerce.

Most of the colleges in India keep 55 % to 60 % as a minimum percentage to be eligible for science stream. 

For commerce course the average minimum percentage is usually 40 to 45 %.

But those nos are just average and they depend from college to college.

In general if the candidates wants to get admission in good science college he needs to score a atleast 85 % in 10 std.

For average college the range could be between 70 to 75 %.

For commerce stream it is easy to get.
