Passed all my ATPL exams first time in 8 months working full time in operations for an air taxi company. And doing my hour building too and commuting (spell chk) 300 miles to see my girlfriend very 2 weeks.
The key for me was always having a BGS book with me at ALL TIMES. So when you get any spare moment... Study!!! I was even known for studying while sitting in the right hand seat before getting my turn in the left where the autopilot came into its own and i did the progress tests..... (only joking)
Did it with BGS who I would very highly recommend!
PS. If your going to BGS stay at Marys.... Great place.
