Would it make any difference to you if I said "no, you'll only get exactly a 44 with that amount of effort", or if I said "yes, you'll still get a 50 because you're in a strong cohort"?
I could respond to this in hundreds of different ways saying it hinges on factors such as your cohort performance in the exam, how much effort you put in, etc. However, I'm just going to summarise it all by saying that at the end of the day, you'll get the score you deserve. One that matches up with the amount of effort you put into your studies for a particular subject. There's absolutely no point in playing the numbers game because you'll start to obsess over which scores are possible and which are now out of reach.
You attributed the fact that you put pressure on yourself as to why you might not be the highest ranked. If that is truly your problem, then trying to compare yourself and calculate the precise scores you need will only drive this problem deeper. Do yourself a favour and just put in your highest efforts, and you might surprise yourself with how you go. Maybe you're being a bit hard on yourself. Either way, the fewer expectations that you construct for yourself, the better off you will be.
I know I haven't exactly answered your question, but I think there is more value in what I've said compared to telling you that it's mathematically possible to get a score of 'x'. Because nobody can tell you that with any certainty. Have a nice day.
