It seems to me that paraffin is pretty light versus its volume (low density). I wonder how much thrust per gram can be generated, and if this will make rockets or jets any cheaper.
I took the (harder) AB test last year, and coding on paper was definatly the hardest part for me. I'm so used to having syntax checking be a click or test-run away that it was very weird to have to remember all of it. The multiple-choice section of the test had harder questions, but was probably easier overall.
How did they grade your exam?
2 parts: Multiple-choice and free-response (coding). The final score is on a scale of 1-5, with 3 being "passing" at most colleges. (*coughs* and gestures to his 5) %)
Did they give you oppritunity to contest the grade if you felt it was graded incorrectly?
Nope. You don't even get to see how you did on each question, so you really have no basis for contesting. That was always my biggest problem with the AP system in general, though overall I think it's REALLY a good thing.
