Progressive studying suits some people like me, and I always need a textbook to guide me through learning, but if you prefer something more dynamic, it will work for you if you want it to. I'd say that if you have noticed that there are things on which you are stuck, you should pay more attention to them and find resources to help you with it until you are sure it's well learnt.
You may post questions here or find materials elsewhere, but only you can tell what interests you the most, I think.
