Go Distance Learning my friend, I did, passed no problems, they were a piece of cake, I also went part time on the CPL (evenings & weekends), hard work but a piece of p*ss, passed first time, now on the IR even easier than the CPL, much more clear cut (you either nail it or you don't), my advice keep working, I'm not in debt and I've got this far. In my view it's a myth that you need to quit work at all, I have a high pressure job too!
