Well 999 that's at least two of us! I'm another beginning life. Also have science A levels, Masters Degree (Engineering) etc. I'm planning to go to US in May to commence training. I have 25hrs but effectively starting from new. Intention is to spend 3 months then return to possibly OATS modular study. Having read posts from fellow Ppruners, I'm inclined to take US exams also; not with a view of converting necessarily but to make best use of my time.
I'd be interested to hear from you and wish you luck. Go for it!
