is newvic good or newham college? maths retake

i need to retake maths but since i'm 18 i would have to do other courses along side if i want to retake for free. newvic offers intensive gcses so i'd have to do 3 other gcses along with it my other ones aren't that good anyway so maybe it'll benefit me but newham i'd just have to do a short course along side with it but i checked out newhams short courses and they're just not it, east ham campus. It does not help me in any way. i mean bumping up a few grades of gcses wouldnt hurt anyone today newvic emailed me in for an assesment and discussing the course so i wonder how that'll go
