UP passers with low grades?

Hi po. I’m currently a grade 11 student and I’m just worried po because I really want to get into UP. I’ve done pretty average when I was Gr7-Gr8, and I got a high general average during Gr9-Gr10. Although, I might be overthinking lang pero I’ve been doing well on majority of my subjects, except for PreCal and GenMath. PreCal is much easier and I think I’ll be able to pass the subject but I’m struggling a lot in GenMath and I feel really discouraged after I failed one activity and I’m nasa star section pa. As in wala akong score. I already approached my teacher about it if he gives out remedial activities if a student has a lower grade. I’m afraid this might take a toll on my grades and my chances into getting into UP. I’m trying my hardest to study GenMath considering we aren’t allowed formula cards sa exam :((
