Query: No clear cut directions on how to solve the problems

I have taken several chemistry courses in high school and college. However i find this book to be very difficult in understanding. I find myself refering back to my old notes and books. There are surely more chemistry books out there that could explain chemistry itself in a more efficient manner. This book does not contain any clear cut directions on how to solve many problems, in addition to containing many problems in the exercises section which was also not explained the lecture part of the book. The practice problems also does not help in solving many of the problems because it is simple and straightforward as opposed to the exercises which is very misleading and unclear. I, as a science major, do not recommend this book unless of course you are required to purchase it by a professor who does not care for you to pass the class.
