Engineering Physics

Reminder: It is also one of the difficult subjects with lots of chapters. Maybe 17 chapters in a book. You might know if you have started reading, getting frustrated some like tearing that book. My way is to read from manual (theory + solution of past question book ) which makes it quite easy for me to pass the exam. I have included some material that will help you to enhance your reading.

If you are Newbie then you should separate at least 10 days for this subject (before the exam) to secure good marks.
and exam gaps can be used for revision. Don’t worry you can do it.
