Swe degree apprenticeship prep in yr 12

I would suggest that showing sporting prowess or an ability to play an instrument is not high on a list of things that prospective employers would be looking for in a student applying for a software engineering apprenticeship. Don't get me wrong, these are worthwhile activities, but you would be far better spending your time on activities that show a prospective employer that you have an active interest in software engineering. There are many low cost development SoC boards that can be purchased these days such as Arduino, ESP32 or Raspberry Pi. Most of these can be purchased for less than £20 and allow you to build your own projects to use software to control motors, LED's, buzzers and all manner of sensors. Being able to demonstrate that you have created and coded solutions for your own projects would be an excellent way to show an interest in the subject and it also shows a prospective employer that you already have some experience, which is a good reassurance for them as some people just do not 'get' coding and they don't want to discover that after taking someone on for a three year apprenticeship. I've seen people do some simple but clever little projects such as sending a message over WiFi to an 'X' account when somebody is detected your room, monitoring the temperature of plants in a greenhouse or automatically opening a secret compartment in your room when a code is entered on a web portal. Being able to show on your CV that you created a few projects and then being able to talk about how you solved these problems in code in an interview would go a long way to impressing prospective employers. Employing someone who is genuinely interested in the subject, in their company and being reassured that they are capable of completing their apprenticeship are the things that are highest in the minds of employers. I hope this helps!
