A situation like yours often happens to people who study well. First of all, be careful, score more carefully, even if you are slow, be steady. Secondly, we should establish a good attitude, and don't always think that it doesn't matter to lose points on easy topics. Leave time for inspection. I used to fold a piece of draft paper three times and then write the draft clearly. Don't think it's a waste of time. Check it later.

If you are excellent, you can take more care and check more when you are on a business trip.
