Study / Revision Technique

Hello,

I’ve finished the groups section now and would like to know if it’s enough at this level now to review this part through working out the notes examples again or I need to go to exam kit and practice some of them for that section. anyway I exam kit is my final revision part after I finish the whole syllabus, but I am only asking at this level when I finish section by section.
Not sure which method I use.
