Engineering Chemistry

Reminder: This is easy subject.Most of the chapter is what you have read in past. Its is (85% Theory + 10% Numerical).Don’t worry !! you can do this ..

If you are Newbie then you should separate at least  4-5 days for this subject (before the exam) to secure good marks.
and exam gaps can be used for revision.
