IPT has been a bludge. Chat, food, drink, internet during lessons. Having said that, however, you need to study the textbook at home, remember all the stuff in it and apply it on the questions, then you will get a decent mark. I mean textbook, not the excel book or other study guide. One of my friend in my class who believes the excel book = textbook and didn't bother to study the school textbook failed very badly (33% in the trial). The excel book doesnt have everything you need in it and is crap.
