Tomorrow Examination!!! First Paper...

Tomorrow is first day of third year final examination...
The subject is Control System. Is a subject consider no very hard for all but since the lecturer is one of the killer in my department (i been 'killed' last time), so everyone also scare the 'suprise' that from our 'good, kind, nice' lecturer.
All the 'TIPS' he gave are very details but we no very sure how high the percentage that we can believe the TIPS..Ai..How suffer I am..
Just like having RM50 in your hand but dare not to spoend it as too many unknonw related to the RM50. Maybe the $ no yours.. Maybe the $ is fake.. Maybe the item you want to buy cost cheaper at other place..
That's the feels... Don't know how..
Haha..Maybe you will say, 'just study all lo.'
Study all is a good way. Memorize the text book the sure can answer the question.
But... May I know who will memorize a book just for answering a paper instead there still got another 6 subjects are going to have test as well??
Ai..Suffer oh..
But can only pray n pray that I can answer at least 80% of the questions....Please GOD...
I need LUCK....
