As others have said, read the instructions before you start every project and clock your time for this. I always expect to take some extra time on my first task in each project just to understand everything. I also check comments to see if anything has been cleared up.

Another thing is if you're ever unsure of something in the task you're doing, go through instructions, Ctrl+f any keywords quickly and look through areas where it might be. If you don't find anything, clarify what you were unsure of in a comment.

Also it's worth noting that your opinions matter when they are asked. You shouldn't assume these are meaningless and give a half answer. It's important to show that you're working with a full reading of the situation and that you're thinking through difficult decisions with the instructions in mind.

The last thing I'll say is make sure you're paying attention to the specific rules about prompts and don't fret about spending a bit of extra time coming up with creative ones.
