Hey guys I’m in 12th grade science pathway, I have three months left until the BacII exam. What are the most important things I need to know to be able to get an A in the exam, I am bad at memorizing so I’m scared for biology and history. However, I am fine in the stem subjects but I want to know what I should do more everyday to get an A.
P.S I study at school from morning until afternoon + tutor until night.
