The test questions are going to test you did your job or not.
It's not very hard questions, they just want to test whether you understand the concept.

You have to work hard, so that you can score well in your test or final.
You have to study, study and study so that one day you realize, it's beautiful theory!
Your maturity on this concept or this subject may not reach that level, so what you need to do is work hard on it, you will not understand the things if you are not putting any effort.

For example, you wish to have ice-cream in refrigerator, but you didn't put any ice-cream there. You open the door and see nothing. You close the door and pray hard so that there are ice-cream in refrigerator. You open the door but you see nothing again.
Praying is not helping when you are not put any effort on the things that you want.

Quotes of dear Prof. Madya Chooi.
There are still many quostes from him.

The night before the 30% test, 

I feel so depressed.

Stressful night.
Pray hard for the test tomorrow. 

I did work hard, perhaps. 

Good luck for Linear Algebra, another subject that kill me.
