You should really study for me it is quite hard
As a student who experienced taking an entrance exam, I would like to give you some pieces of advice to ponder on in taking an entrance exam.
First, Remember those past lessons you had during your entire high school life.  I will not be particular to the topic but mostly, this includes your skills in Language, Reading, Verbal and Non verbal type of test, solving problems, analyzing situations and other lessons just like in science.
Just focus to what you're doing during the exam, always think positively.
Study hard!...Good Luck on you dear!!
