Q2 or Q3 should be done first atleast. that boosts confidence recommend Q1 at the end but grab all easy marks like, evidence, issues, procedures. you can give up some AR, ROMM, or BR but above approach leads 95 percent completion and you will do the job
may recommend you plan as well. Go for easiest question first where you can go very well & the difficult or lengthy should be at the end. trust me AAA is testing exam writing strategy as well. i got it after 4 attempts but tested this skill too
