Hello,

i like that you are interested in working hard to make the marks you want. 8 months is ok as long as you discipline your self to work extremely hard to get the marks you desire.

i also advice to make a schedule that fits you as a person, but note that you have to be determined, focused and true to yourself.

make your concepts clear, study from the right material and answer past questions. Don't forget to try mock exams.

wishing you the very best and I hope you get the marks you desire.
