I have my half yearlies this term and not sure if I am actually studying efficiently for Bio. I had one teacher (he was alright) last year but he got swapped to different classes this year. Just my luck, I got a new one that does nothing meanwhile the other class has an amazing teacher. I'm trying to do practice papers but I can't tell how my progress is going. I'm tied for 1st so I want this to be my chance to maintain that rank. How can I ace the exam?
