Btec

I got a near pass in 2 of my external exams in yr 12 in yr 13 im re taking them so i can at least get a pass. Any suggestions on how to revise for them.
Btw im doing level 3 extended diploma in engineering. And the units are 1&3

Wouldnt it be the same as any exam?
Master core material via specification and check for examiners reports.
Make revision notes, so you understand it all.
Check for exam papers on exam board website or source of questions.
Check for mark schemes and examiners report on exam board website.
Practice timed questions.

The problem is that i can't get the revision in my head
