Which Academy to join for prep of fta indigo cadet programme

I just got done with my class 1 medical today and have already decided to go for FTA indigo cadet pilot programme but I am confused on how should I prepare for them. I looked into self prep but ill have to buy alot of equipments so I am just thinking to go for the academies since ill also have a structure. I have seen that online golden epaulettes is pretty popular but the some reviews are making me skeptical about them. So what academy is worth considering for my prep for the selection procedure.
