My binder was also too heavy. So I solved this problem in two ways. First I got a file cabinet. The second thing I did was get separators for math, science and social studies. Since the separators don't hold papers, that means you have to put the paper in the rings of the binder which means you will need a three-way hole puncher.
Some papers already have holes.
P.S. Don't forget your pencils. In the binder that's opened there are separators.
