How Far Can My Hopes Reach?

Is it okay to still ask Allah for things when deep down you feel you don’t deserve them, and you know you could’ve put in more effort? When you slip into sin sometimes and your prayers aren’t as regular as they should be. I wonder if I should pray for just the half-good outcome or go all-in and ask for the absolute best. I’m scared because I’ve been making du’a so intensely for the best, fully believing I’d receive it. Now that the results are coming closer, I’m terrified-what if I keep begging for the best and end up not getting even half of what I hoped for? I know this sounds childish, I’m sorry. But I’ve been working toward this for two years. Please, please make du’a for me. I honestly try my best, but I also think I might have some kind of neurodevelopmental condition, and it’s just… really hard. I want top results this semester, and my finals are happening now. I sat down to calculate my possible marks, and they don’t look like what I was aiming for. Not even close. I’m sorry for rambling. I just really don’t know what to think. JazakAllah khair for reading.
