Getting a solution manual is always a mixed bag. If you rely on them too much you may not actually learn anything and will not be doing yourself any favors when it comes time to take an exam. However, Calculus III is probably the hardest class in the calculus sequence that anyone who wants to go into engineering or get a physics degree has to take, and the problems can be hard to figure out, especially if your teacher is not all that great. The textbook to which this solution manual is keyed is so useless and has so few examples, the solution manual is almost required to figure out how to do the problems. The book is not going to give you much guidance at all so the only way to quickly figure out how to do the problems without camping out in your professor's office during office hours is to use this.
The problem with this thing is that it only has solutions for some of the odd problems, and it does have some errors in it. And because it is a solution manual, it just shows the steps (although it does not always show every step, and sometimes omits crucial steps) and does not provide any explanation for why you have to do things a certain way. So, if you do not understand why the problems are being solved the way they are, you will still be lost. But, it will give you some worked-out examples to go off of which is better than nothing.
