Well first up sorry if I've posted incorrectly :-( secondly i need a bit of help . What it is is i am currently at college studying maths and English gcse equivalent part time and for the career path i am have chosen (early years teaching 3-5yrs possibly primary teaching). Unfortunately during my school days i was far from the perfect student i seen being the class clown enjoyabl "boring" education i regret it now but am trying to do something about it . so im on my level 1 maths and English gcse i think that's the equivalent to a (g-d grade ) and am flying through it and am due to do level 2 soon (the equivalent to a-c grade) however i need to do science even though at school this was my best subject concentration and failure to revise resulted in disappointing grades so i have been looking at doing a gcse re sit and can not find anywhere near me that does this (im from Warrington cheshire btw ) so i am after bucket loads of advice on what to do ,where to go . do i keep searching for colleges that do this or do i do it as a distance learning course . if so what one is the best and cheapest to do also any advice in regards to the teaching would be fab . thanks for reading xx
