Still... If you want to study by his book I would suggest you do every single exercise. Otherwise you'll miss a lot of important stuff.
I agree that Griffiths is not a great book to study QM if you want to learn enough QM to get you prepared e.g. graduate level QM (or even advanced undergrad QM). However, for the OP, for their very first course in QM, I think Griffiths is a great introduction. Sure, it's not super rigorous, but I think Griffiths stresses conceptual understanding over mathematical rigor, and I think this is a better approach for someone's very first course in QM. Also in my opinion, as someone who is not interested in learning all the rigor of QM, I am happy with my surface level conceptual-based QM from Griffiths (all of my undergrad QM courses were taught out of Griffiths--my senior advanced QM was the perturbation theory chapters at the end of Griffiths).
