I am a private candidate, and I sat Chem AS units in June and cashed in for IAS. I wasn't satisfied with my grade so I decided to resit U1 and U2 in October and cash in for IAS again. I didn't resit U3 (which I took alr in June). My U3 ums will be counted along with U1/2 for the new IAS grade right? (edit: accidentally posted this in the wrong forum lol)
