In 1 week i'm going to get an OP prediction based on my results and im really scared. They said if you get 6 C's you get an OP 20! And i failed 2 Subjects!!!
Here are my grades:

Biology: SA7 (C+)
Chemistry SA8 (C+)
Drama: HA5 (B)
Chinese: LA10 (D+)
Maths B: LA10 (D+)
English SA7 (C+)

I'm fairly certain ill get an OP prediction of 22-25 and my parents will murder me. I have big plans for next year though, I'm hoping these will be next years results, could you tell me what OP i would get with them?

Biology HA8 (B+)
Chemistry HA1 (B-)

Drama HA5 (A)
Chinese (HA1) (B-)
English (HA5) B

I'm going to work my ass off next year and try to get an 8. I know i probably need all B+'s to get an 8.
