In college they will accept 3/4 GCSES but the grades should be at a grade C or above. The GCSES they will need are Maths, English, Science and the more the better.
well the recommended is 5 gcses at a*- c. but it depends on the sixth form your going to. most also take equeverlant to gcses to like b-tecs. The best thing to is too email the college
Well, A-level is the more advanced, being taken at college or sixth form, afetr your GCSEs. However, your GCSEs are also important, as both employers and universities take your GCSE and A levels into consideration. It is common to take around 10 GCSEs and 3-4 Alevels.
I don't think you need any gcses to be a bricklayer, I think you can do courses, nvq's at college to study it though which is quite usefull have a look at your local college:)
