pass the JLPT 2 test

I am going to register for this year’s test in Dec. I’ve learned some Japanese in college. The book we used is called “Standard Japanese”. It has the beginner and intermediate levels. After you’ve finished the latter, you are supposed to have the ability to pass JLPT 2 with some preparation. I’ve finished that, but since it’s been almost 5 years and I forget some of words and grammar. I hope I can recall most of them with four months…
