Yo, I feel ya. Had similar probs in psych last year. First 2 SACs were trash, like below 60%, but then I pulled a 80% on the next ones. It's def possible to still hit that 40 study score. You gotta ace the rest of the SACs and kill the final exam tho.
Also, talk to your teacher about extra help or resources. Practice heaps, do past exams. Don't let those early scores get you down. You got time to turn it around. Stay focused and keep pushing. Good luck!
