chp380

Hi everyone, I recently took a GRE Subject test, and I got a shockingly awful score (620 out of 990), while actually I was expecting it to be at least 800. It means I must have answered about 20 or 25 questions wrong out of my total 54 answered questions, and honestly, I doubt that I have done such an awful performance in exam.Therefore, I am considering a re-scoring request, but since it will cost me US$50, I wanted to know if it worth it to be done. I mean I'm afraid that the score wouldn't be changed by ETS, and I just lose some extra money. I really appreciate it if anyone can share his/her re-scoring experience with me. Thanks
