Examiners comment on questions which most students got wrong and explain it how should have been done and etc, no not all questions are like that. Practice the specimen paper, you will get a better idea what type of questions might come in the exam
And just as important is to have a Revision Kit from one of the ACCA Approved Publishers because they are full of exam standard questions for practice. Practice at as many questions as possible is vital to passing the exam 🙂
