IEB has too much to study

OMG! The IEB textbook is too difficult for me man. I have not touched the book at home since the first day of school. lol~ The MCQ test has 50 questions. From A - G, there are more than 150 pages i think. lol~ I have only read 25 pages only so far.
I think i will GG when I do the test when school reopen. rofl
