So I have a lot of things to repractice. Its kind of annoying. So what is the fastest way to repractice lessons to catch up with new lessons?
Depends on your style. If you took a few months' break like I did and aren't super confident on too much, you could go through each skill and just practice the "weak words" once or twice till you feel good about it. Or you could just keep doing the regular practices till you're not lost and getting a lot wrong. It shouldn't be that hard to refresh yourself, and a day or two should be enough to re-gold all your skills (if that's important to you).
