Wanna learn to do something, maybe ollie

Hey, so i'm a beginner and I'm just starting to get down crossing over both wakes(not jumping-crossing). I'm mainly falling on the second wake going toeside, but I think I'll get it down soon. So my question basically is, what should I start working on next? I would like to do an ollie, read up on how to do it. Just seeing if anyone else can explain it better, as my attempts were unsuccessful. Anything else good to start learning? I have a few more w/e's to ride, would like to get something down before the end of the season!!!
