I think the best thing I can suggest is simply taking a little time to digest things, not worrying too much about progress, and just enjoying the process of learning. It can be easy to get stressed about stuff not going in, but re-reading the mnemonics and thinking over the meanings and readings can help. I also find setting notes with some custom mnemonics can help if you can think of a way to remember the reading that fits best in your head
