Few high-level advices, in arbitrary order. 1. Don't panic. If you don't understand everything immediately, that's normal. Try second or third time - and even fourth and fifth. Not necessarily immediately - take some time. 2. Try different books - for different people different explanations "click" differently. 3. Math is often understood better a few months after you studied the material. In many courses you don't have time to internalize new concepts in real time - but after some pause you feel better adjusted to them. 4. When you see a math expression, read it aloud, for better understanding. The goal is to force you to actually pay attention to every feature of the math notation used. Even reading this once helps. After reading a few times, you may start to see patterns and understandable pieces of the expression. 5. Scientists sometimes need quite a bit of time to understand what their peers - even in close areas - write in their papers. Reading one paper, even not too long, for the whole week to get a good understanding could be normal.
