What's up man, welcome. A huge tip is to dissect your rolls at the end of the night and then watch the proper technique for what's missing in your game. The move's they teach in class are great, but you also need to find out what you need for your're game at the moment. If you noticed that all night, every time you got yr guard passed and you never recovered,, when you get home search for guard recovering techniques, drill those. If you notice every time you get someones back and you have trouble choking them, search for hand fighting techniques,, transfers from the back to spiderweb,, exct.
This will speed up your learning curve tremendously. Good luck!
