My opinion on Success of Theory against mathematical problems in engineering

I personally feared of solving problems in first sem of apm subject.
All professors guided us to prefer firstly Problems in order to pass in exam.

But I experienced myself that with just only theory we can pass, also subjects like control engineering.

I have also seen that my friends who are most active in solving problems got ATKT from first year to last year.

SO Don't fear of Problems you can PASS Exams by just theory also . (Shivaji University )
