I took it this last monday. My advice prepare yourself on math, there isn't a lot of time. The Math is dead on. A lot of percents..averages.. that shoul be somewhat easy. Just keep an eye on the time, towards the end I had to guess on a few. Science you really need to know the scientific method, the earths plates.... clouds... know the conversions from celsius to F and visa versa. Grammar know when to use colons and semi colons, because most likely it will be a comma. There is about 5 spelling questions...and know what a simple subject is. There are 170 questions. I had 2 weeks to study.. I thought during the test I failed, but I PASSED. I didn't think the test was easy. But then again a lot was riding on it.. If I didn't pass I would have to wait another semester to apply.
