jarrellebarton,

It sounds like you need level five on the traditional HSK. This is a low-intermediate level (the traditional HSK scores from 1-11) and is usually the level they ask for admissions to university. And congrats on going for the Chinese language classes too.

If you're asking for advice, I'd suggest going over the vocabulary lists here and looking for words you don't know. Don't worry about memorizing the words you don't know -- it isn't that kind of test. Just try to see which words you don't know since they're all pretty high frequency. Maybe there will be a pattern. Then focus on taking all the Beginner and Intermediate sample tests you can. You should be able to do really well (consistently) on the beginner tests. But the Intermediate tests will probably be a bit hard. Assuming you're still in your free trial print them all off or save them or something.

Just on a personal note, the hardest thing for me the first time I took the HSK was the reading exercises. I don't know if there's any way to speed this up except more reading. Good luck. :)
