This week in comp sci/ap studying

This is the last week before the ap and comp sci is starting to get a bit more serious. The ap is a pretty big deal, and is basically a final for the course, so I am starting to rack up my studying. I have been reviewing and found that some of the more simple concepts have started to slip my mind. I forgot how arraylists worked, and the majority of Gridworld, and have been frantically trying to relearn that for the past few days. Inheritance has also caused some problems and I am still nervous about the free response questions. I hope to get a five on the ap, and I have started getting scores in that range on the practice tests, but i am worried that it is more likely that I will get a four or three. A four would be acceptable but a three would be fairly bad. I am concentrating on studying now and just hope to be ready for my test on Tuesday.
