What I have noticed in Physics and Math is that sometimes there is a key concept that everything revolves upon. I had forgotten all math for a long time and only took it up in Israel after I became convinced that it is not separate from Torah but a part of God's Law.
At the time I bought a small book that had  basic concepts of Math. On one page was the idea of of a tangent function laid out simply. To my surprise, I understood it [only after review]. Then in Hebrew University, someone showed me the basic idea of how to solve an algebraic equation, and [the same person] later the basic idea of a derivative.
Over time, I began to see that for me there were certain points of leverage or focus that made everything else clear.
It might be different according to the person. But for me, I found it useful to identify key points, and review them.


I also think that often a lot depends on finding the right book.
Furthermore, the idea of "Girsa" [saying the words in order and go on--as fast as possible] I think is important in the way it is first introduced in tractate Sabbath [I think around page 63]. ליגמור והדר ליסבר "to finish, and then to understand" [delve into it deeply].
