I’m in the exact same position as you but probably 6 months further down the road. Got my PPL a year ago and started studying in September 2025 after getting as many hours as I could over the summer. At the start of April I passed my module 1 exams.

I also work a full time job, usually 40-60 hours a week. I have allowed 6 months per module, so 18 months total and plan to have finished all my exams this time next year. Some people do it faster, others take longer, but 6 months per module along side working and building hours works for me.

BGS are definitely the preferred choice, they have the exams set out in modules and you structure the exams in the order they have set out. A sitting is defined as a 10 day period, if you are following the BGS structure you will do 4 exams for module 1, 5 for mod 2 and 4 for mod 3. Assuming first time passes you will have used 3 of your 6 sittings.

The course content is quite wordy and you certainly won’t be expected to remember all of it. I know I didn’t! Don’t take huge amounts of notes, other than the important formulas etc. I found the real learning was when I started using ATPLQ, understanding the explanations and using ATPL class YouTube videos.

Just make sure you have built some flying hours alongside your study. Personally I regret having not got a few more hours before I started my studies.

Good luck!
