Personal issues are really subjective. It's called the "help with life" forum for a reason, so if someone has an issue with their grades that is really bringing them down and would appreciate some advice on how to do a bit better in school, why not come to the forum with the most appropriate title to suit their needs and try to avoid judgment from people like you?
If you really don't like the forum, you can leave. If you want to do things for those who are seriously experiencing suicidality on here beyond suggesting that they seek a professional (after being told that so many times, no wonder why post-counts are low for more "serious" threads on occasion) then do that.
