That is the EXTACTLY reason that I failed in my last A-Level Exam and because of this reason, I must wait one more year.
There was 5 subjects in my Exam. Pure Mathematics is my best-prepare subject but I just scored E........TIME, is the main problem, I spend quite amount of time in a difficult question and cannot slove it. After that, when I due with the remaining questions, my mind was in choas 
!!!!!!
At the fews months before my exam, I almost abandoned PR.
To well prepare the exam, I must do about 10 years past paper in every subjects(except Chinese and English)
That is what every students in Hong Kong do to due with the public exam.
every teacher also advice us just study the textbook is absolutly not enough
Do anyone here have any experience about preparing public exam
e.g.SAT & GCE A-Level
P.S. Hong Kong A-LEVEL Exam is the most difficult Exam in the world, I think
