Hi sorry!
Got busy so will reply now
Yes you can wear Fitbit / Apple Watch totally allowed (I wear mine all day)
When you land isn't counted as a day off that's just the rest of your duty day (which is good for mel base most landings are in the morning)
Training in gs for EPs was very not 9-5, some 6am starts some 2pm starts
But you're all in it together so it works out fine, plus free instant coffee in the training centre!
Days off in ground school for me were mainly single days off with one full weekend
Also cca320 ask your dentist to email it to you and just get it put on a disk at the library
That's what I did
