WST,
Although you can probably remember the answers given to you here, it won´t help with your overall understanding much. If I were you I would draw a side view of a runway on a white board and go through each limiting factor and draw it on the board.
EG, draw the ASDA, the s/e climb out dry screen height, s/e climb out wet, the four climb sectors and their %, the net take-off area. Spend an hour or two putting different obstacles into the drawing and seeing what it will effect, draw take off rolls and flight paths for different flap settings etc.
The whole takeoff performance subject makes a lot of sense and is not difficult if you view it completely and from a bit of a distance rather than getting in too close.
If you just want answers for an exam then that will be a bit too much like hard work. If you want to be a proficient airline pilot it might help. Also, keep in mind that answers on a web site may or may not be correct and need verifying.Hope that helps.
