In reply to everyone:
thanks guys for all your helpful comments. its really good to hear from other people in this field or people that know certain things about it.
dauphin: thanks for the positive comments. i agree a lot of people do go into medicine even though its not their 'calling'. i know a few friends in this situation who did it just to appease their parents. i thought my calling was banking, how wrong was i when i filled out that ucas form back when i was 17!
nickinscottishmountains: kudos for you for starting late! wow i am truely impressed! i bet you received some strange looks when you told your friends that you were thinking about doing it. how many thought it was just a crazy idea?! the main reason for a 4 year course over a 5 year course was that i'd be finished sooner so would be able to start working and earning $$$ a lot sooner. alongside the fact that i've got a long term gf who i wouldn't imagine would be overly happy having to either commute or move to come see me etc. also seeing as though it would be an intensive course i'd be able to hit the studying hard and basically adopt the studying as my new 'job' rather than fall into being a student again and having too much of a good time if you know what i mean. if i had more of a choice i think i'd prefer the 5 year as like you said you'd have a bit more of a work life balance.
leroy brown: thanks mate, i may be taking you up on that offer, its much appreciated.
kellykettle: thanks for the advice on doing chemistry is definitely something i'm thinking about doing.
vark: good point. i had a feeling i'd be showing a defeatist attitude by grumbling at doing an a-level whilst holding down a job.
my gf is a pharmacist and spends a lot of time doing further studying so i kind of get the idea how much extra work is needed just from looking at how much work she does!
katiep: thanks for the comments and good luck with your course
stevep: very good advice re the work shadowing. i can only imagine that it must feel like the best job in the world at times, but at other times often the worse. especially when having to deliver bad news etc.
definitely has given me things to think about!
helsba: some great points there thanks a lot for those. you're right, getting the a-level shouldn't be a big hurdle, i just need to get my @rse in gear and get organised.
thing about moving is quite a difficult hurdle though...think i'll need to discuss this a lot with my gf. (at the mo she's got a very good job as a pharmacist in a london hospital and is 15 months into her rotation there so doesn't want to move!)
kemics: go for it! as we've seen here there are plenty of people who have started later on in life. i guess though that some uni's may look unfavourably on media studies as an academic subject (not my own thoughts btw) so may require the science a-level(s). don't worry i'd speak to a careers advisor or contact leroy brown in the thread earlier.
thanks again everyone
