I'm not sure if this is a good or bad thing.
1. For some papers, seeing the grade boundaries usually makes me feel more confident and certain in achieving my desired grade(s), which makes me less anxious when opening results.
2. For others, where i feel my score is more marginal/near the grade boundary it causes me to spend 24 hours agonising over which side of the grade boundary i will fall on.
Overall I think it's probably a good thing bc spending a day religiously studying the grade boundaries and trying to work out my mark/grade was never fun but i could never stop myself from doing it anyway.
