I am honestly upset with my attempt

I gave my first GRE on 19th July and I was honestly expecting so much more marks cause of mocks! But the actual paper was so much different for me, i am not making excuses, its lowkey my fault..... I was so worried about screwing it up that I stressed too hard.... anyways i only got 304 (153V, 151Q, 4.5AWA) and I am so disappointed in myself??? I was genuinely expecting atleast 310+ and honestly growing up, maths has always been my strong point in life but to only get 151 was quite a shock to me, I wasnt expecting a 165+ but I was hoping to get atleast 160. I don't even know if 304 is good or bad tbh? but as somoene who wants to do masters in CS, I know for a fact 304 is less and what kind of STEM student am i? If i cant even do basic mathematics.
