You can get to this screen from my chance button or options menu.

Scores are computed as the percentage of the sum of all scores. Hence, share of each topic (viz., Physics, Chemistry, Botany and Zoology) is 25% only.
Below is the table depicting how scores are graded. 

Score Range Result
less than 10% Poor
10% - 15% Average
15% - 20% Good
20% and above Excellent
