UCL neuroscience

i'm going into year 13 considering applying to UCL for neuroscience but i'm worried my gcses will hold me back... the ucas website says around 2 in 5 people receive an offer for neuroscience at ucl even with the minimum grades. i'm predicted A*AA in biology, chemistry, and psychology respectively and i'm doing an EPQ.

my gcses were 9888876666 and the 6's were in maths, chem, physics, japanese

i've checked their website and they only require a 6 in maths and 6 in eng lang but i know this doesn't mean you're guaranteed an offer... do you know anyone who got into UCL neuroscience? am i unlikely to?

also, what can i do before the ucas submission deadline to boost my application?
