Future career concern

Your grades will not necessarily affect your chances of going into the career you want, to an extent. It all depends on the route you take i.e. university, apprenticeships internships/placements etc. The best thing would be to study hard and get those grades up but try to develop some of the skills that are sought after. You can also leverage LinkedIn to network and connect with people in your field. They'll give you great advice and some might even provide mentorship opportunities. Just have a genuine interest in the field, stay up to date with relevant current affairs/developments and be proactive with your development. Hopefully all goes well and you'll be swimming in £££.
