study bitterly

As a candidate of SPM by this year,all that we do everyday is STUDY,MEMORIZE,and UNDERSTANDING!..
The concept,
The formula,
The fact,
The skill,
Etc

I knew that the time left for the major examination is about 19 days,it's around the corner..
Pretty soon I have to deal with all the exam papers.
By holding my ink pen,squeezing out a correct answer from my brain,stay alert when the exam is going on,read the question carefully,and so on..

I had realised that my common mistakes is the main point of losing marks.
Thus,I forced to enchance my alertness by doing a lot of test papers,learn to be focusing accurately for each question..
Hopefully all of my mistakes are under control..
