Seeking advice for a new player...

[mnloa201]

Greetings everyone,

as the title states, I'm relatively new to SM and I am looking for some advice. I've been playing for roughly a month or so. I started one handed but have since switched to spread. At this point, I've just gotten my first AA on Vertex Beta, so that will give you an idea of where I'm at. So on to my questions...

The things I have the most problems with are:
1) Accuracy - my MA is pretty awful...any tips on ways to improve this would be nice
2) Stamina - Can barely last through Vertex Beta, have to push through it. Should improve with time though I imagine
3) Jacks - I can't do jacks at all really...I'm using a crappy keyboard that came with someone's Dell computer. I'm thinking, or hoping, this has something to do with. Some searching said I should practice vibrating to improve jack speed. Is that just what it sounds like? Some clarification on this would be nice too.
4) trills - my timing is just rediculously bad when it comes to trills. No idea why, when it comes to streams I do fine, but even with relatively slow trills I'll end up getting a "Good" here and there. Very frustrating.
5) Fast consecutive jumps - can't handle this well either...Vertex Beta has a few short sections like this, and I've only recently been able to get through it the majority of the time. Does this just take practice?

Those are my main issues. This seemed like the best community for SM, so any advice is appreciated. thanks
