I am currently on tier 1 entrepreneur extension completing my 10 years completing on 2nd September and will go for same day premium appointment within 28 qualifying period in Aug. Also, I am completing my tier 1 ENT 5 years in June and same as my wife as a dependent but wont take risk due to number of silly refusals nowadays so I decided to go for 10yrs LR. I am aware my wife;'s clock reset to another 5 yrs

My wife is switching to FLr(M) and she has already taken B1. If I look at 04/2018 FLR-M form its only shows to select A1 or A2 and no option to select ABOVE?
Can you please advise if B1 is still acceptable as its higher but where to fill this on the form?
Many thanks- IR
