Mid student taking IB

Honestly I just want to hear everyone’s stories so that I can feel less conflicted on which qualification I should take. I’m genuinely a pretty mid student I’ve never gotten top 10 in my year (wasn’t in top 20 last year), I don’t even know if I’ll do well in ib and get high scores enough to get into my dream schools. Of course, I dream of getting 40+, but I’m genuinely pretty mid and don’t have the best time management and I don’t know if that will be possible for me. Has anyone who’s currently doing the diploma or has finished it has/had similar experience like me? Is it realistic to still score high?
