⚠️ EXAM STRATEGY & TIPS

Do not rush into answering questions.
Don’t waste too much time on questions you don’t know — skip and move on.
Start with questions that don’t involve calculations to save time.
Always crosscheck your answers.
Don’t be in a hurry to submit — you’re not in a competition.
Don’t be scared — getting an A is very achievable.
Don’t be overconfident either — calm your blood, no be only you sabi book 😌.
If you have any complaints, corrections, or feedback, please use the comment box.

Please I don’t know if it is the website or my phone. It’s hard to change my answers. When I tried doing so, it might end up picking another answer or just not pick any. Meanwhile an indicator shows that one answer has been picked. In the end the website shows that I didn’t answer the question in the end.
