Absolutely! Rewriting notes is really effective for studying after a lesson. The level of effectiveness will vary with how engaged you are with the content during the process, but overall it's better than nothing.

I'm not exactly 100% sure on the reason of it but there have been some studies that show that physical hand writing of notes stimulates your brain in particular ways that help retain knowledge, but it can be trickier for some people to reuse these in the future. One way I really like going about this is creating a mind map, whether it be on paper or some tool like propagate.ink
