<p>Solution manuals can be a good thing or a bad thing, depending on how you use it. Obviously if you just copy everything, it’s not good for you. If you copy it, and try to understand it, that’s a bit better, but you’re still not doing any thinking for yourself. Ideally, you’d try to figure everything out yourself, and only resort to the solutions when you’re ready to give up and would’ve skipped the problem otherwise. It’s better than not ever knowing the answer.</p>
