I feel like a failure even though I passed

Please do not post this anywhere else. I'm probably going to delete it later myself I just want to vent a bit

Exam results came for my final year of high school and it just felt like a punch in the gut. I passed the year on non exam assessments alone which is usually how I pass every year because I struggle a lot on exams and just never do well on them.

This year one of my best classes got an exam which I passed with really good marks during the practice but found out I had failed the actual exam and it just sucks because it was one of the classes that I thought I would do well in even in an exam and was really happy with my answers. but it turns out I failed. For my art class I passed it with the lowest passing mark when for the past years I had gotten the highest mark and the art class exam is actually just a massive year long project. Additionally I failed another exam for a different class which I spent a lot of time in class working on. and in a cruel twist of fate the one class that I was struggling with and didn't really have my heart in I passed which sucks.

I thought I did well I was proud of myself only to be told that it's not good enough and even though I passed the year with the non exam assessments I still feel like I disappointed my teachers and myself with the exam results. I don't even know why I am writing this I just want to vent a bit because I should be happy that I passed the year but I can't stop thinking about the massive disappointment I am to myself. I may not be the best student but I genuinely thought I understood and was capable of passing these exams or getting a better mark on my art project.

I'm sorry for taking up time I Just needed somewhere to vent about this
