Had the same issue. Something that has helped me has been keeping an eye on the clock (but not too much that it becomes a distraction) and ensuring that I don't waste too much time contemplating a difficult question. You have 35 minutes to answer 25 questions, roughly 1 min and 30 seconds a question. Try to keep that in your mind and execute it. What I aim for is 45 seconds to read the question and 45 seconds to answer it. Any longer you should guess and move on. Of course you might answer some questions faster, leaving you more time for others and vice versa.

JY you're usually the man but this explanation had me lost
