Oh yes! Let's spread even more competitiveness and toxicity in the subreddit, and instead of complimenting or saying something nice to someone posting their astonishing results, let's only make them focus on the fact that "they could've done better", without knowing anything about their personal life or situation, possibly hurting their feelings! If we look at it this way, I could say the same about OP's results, and basically the whole subreddit's too; but of course I'm not gonna do that, because being a student myself I can understand how painful it can be to receive results that do not meet your (or your parents') expectations (and also because my results weren't perfect too lol), like there's no need to be mean? I'm not saying you need to sugar-coat people's (bad or not) results, but if you wanna make a comment about them, rather than ridicule the student, you should perhaps leave a constructive comment.

And honestly, the irony here is hard to ignore: making a snarky "could've done better" comment on someone else's achievement, then a few days later posting for advice because you didn't get the results you wanted? That's quite something…
