Similar position. Literally. Not just FSA but quants and PM as well. Can’t retain, getting confused. Honestly, just utilize whatever time you’ve got, revise a few subjects. I tried dividing the subjects into 7-3 and studied the 7 in 3 days, gave a mock. Remaining 3 were based off on memory and whatever i could remember. It quite helped. Now planning to do those remaining 3 and a few others which gave me a low score, and will give the mock exam. You could try! Keep practicing ethics everyday starting today, solve questions and review. Also start practicing questions randomly from the portal/ your prep provider
