I've only done Bio Paper 3 and Physics Paper 3.
Bio paper 3 was...
I don't know, I didn't follow the safety procedure for the lab, I think they'll deduct some points out of it. For question 1, the fourth solution (S4) contains the most starch, the first has no starch at all (S1), but S2 and S3 were interchangeable, I was confounded. (The S1 through S4 is the same for each school, right?)
For question number 2, I measured the WIDTH of the guard cell instead of the LENGTH.
Question 3 was just okay.
Physics paper 3 was also quite a failure for me. Question 1 was good.
Question 2 was awful. The threshold weight kept changing. I repeated about 10 times and it kept changing DRASTICALLY! From 260 grams, to over 500 grams. The feeling of desperation all come back to me just as I talk about it.
(By the way, I got all 'U's for all paper 3, I'm currently retaking them. I'm hoping to get at least 'E' this time around. Maybe I'm just retarded in the field of Paper 3)
