Hello.
I'm sorry that you're feeling that way about your sac.
Your chances of obtaining a 40+ study score are
not ruined. At all! It's only one sac, so it's not going to completely destroy your study score. I know this is true because I thought I got so bad for my first biology SAC last year. It was terrible. I felt really depressed. That was my worst sac score for Biology. However, I still ended up getting a 40+ study score and I had ended up getting A+ for both GA1 and GA2.
I would advise that you look ahead for your next sac, instead of dwelling on this sac because it's done and over with and you can't do anything about it. However, you can change your next sac score by working towards that goal and improving.
Also, it's worth pointing out that you haven't gotten your score back, so you may have gone better than you expected.
Don't be disheartened. It's over with and you've done it and you can still achieve that 40+ score!
I hope you have a great rest of the week too!
