i have just open this new thread see whether it is necessary to buy a textbook combine with a study guide. i have check out the price for those textbook i want (like conquering chemistry, jacaranda physics, etc) and all of them is like 50-70 bucks, comparing to a excel one for 30.
so do they have the same content? is it necessary to buy both of them? if i use it for study in exam, which one will be more useful?
