All doubts cleared at one go

Basically when i was attempting 300-630 practice exams, i had no doubts at all. This was because practice on these questions on a regular basis clears the doubts on it own. So i was weak in this particular topic - advanced aci policies and integrations which was of 25% weightage. I wanted to master it because of its weightage. I could through practice and i achieved 930 in the Cisco DCACIA exam luckily.
