Band 9 to band 7 in one year opinion, change, studying, multiple, earlier

JGovender

I am faced with a band 7 after a band 9 one year earlier. A band 7 with more preparation and a better exam done in my opinion.

I was practicing past exams before the actual exam and was scoring above 70% in both essay type and multiple choice questions.

I answered all the questions.

I don't really know what to do.

How to start studying again. What change should I bring about in my studying approach.
