Hello! For me, I prioritized Module 1 which is mostly about Chemistry coz it has the biggest percentage. It is 20% part of the exam. Add Module 4 which is about Pharmacology. It would help you a lot since you can connect it to mostly all the subject.You can ask your school about pacop reviewers because our school provided 1 for us, and the rest were from my friends which are very good at looking for one ? I photocopied some of it.The review center I enrolled also provided us some pacop too. God bless on your board exam Shirley! ?
