Are you fan of carrying thick books in your major subjects on your hand?

I just want to have one notebook with me, any other bokk not all.

When I studied by post graduation, I never use to carry the books except 1 note book to take down the point. My residence was near the college and college library was few yards from the college. Therefore there was no need to carry to books everyday. Once or twice a month, I used to borrow the books from library.
