Thanks flyinho, i think you're right and that it may just be the case I will have to work hard to improve my mental arithmetic. To be honest I think if I took one of the jobs I would be at a serious risk of getting stuck there and ultimately not pursuing the dream. I'm fortunate in that I can raise the funds to go the Integrated route and I think this will be best for me...I guess life isn't a rehersal and the best thing is to go for it and work as hard a possible to achieve your goal!
Bandit, i appreciate your frank comments and think commitment and a lot of hard work is definitely going to be required! I would imagine the studying to be pretty hardcore but I'm used to that, thanks to uni, so fingers crossed I'll cope fine.
I think my decision is virtually made, best put together a 'thanks but no thanks' reply for those job offers lol...some will think I'm crazy but nevermind!!
Cheers for the comments guys.
