That depends. Think about this, most of the first 20 problems will be counted towards your total score, while the last 21 contain most of the experiment problems. So you'd be better off making sure the first 20 are done right. However, if you are so damn sure that you do the problem right, you do not have to drag on for 2 minutes. Just read and think more carefully for the first 20.
I do not know much about score.
For your reference. |
