At the moment me and two fourth years are basically writing all the code for a single seater formula style electric race car. This means Motor controller, battery controller, HUD, sensors, telemetry and getting it all to communicate. (on the way having to learn a lot about control, signal processing and learning a new platform) Its by far the most complex system I've ever worked on and coming together really well - the guys I'm working with really know there shit.
I got BBC(Maths,Physics,Chem), My attitude to A-levels wasn't exactly great...Its not that bad tbh - Work hard at uni and you'll easily leave people that did much better then you at A-level behind in the dirt :) Also AAB gives you 340 ucas points which would be fine for every job I've seen.
ECs are Formula Student (Mostly embedded systems stuff, also did a lot of sponsorship getting organisation type stuff last year), Cyber Security Challenge UK (Got invited to a conference, have been told to keep the dates of two more face to faces clear...) and general member for one of the uni's bigger societies.
A lot of finance companies have rejected me for placements for low A level grades despite high firsts in all my CS modules, solid extra curricular's etc...
