Congratulations to you!
Past questions helped my life as well. I remember when I had to study every night for six months just to get the highest score as possible in order to gain admission into my preferred course. It paid off at the end.

Reading notes is good. But practicing questions help you identify the knowledge gaps so you can fill them.

Our train our brains to recognise information when we read but active our active recall abilities when we practice answering these questions.
