Future Learn
There are many courses on this site that relate to future careers – some are listed here but if you search you will find many more. All courses are free and you can pay for a certificate but you DO NOT HAVE TO DO THIS. You can reference the courses on any application, including your UCAS application, without having to pay. The courses run with a set amount of hours per week and you do them independently, at times that suit you. Take a look, get ahead and keep a note of everything that you do. Keep your notes too so you can refer to course-specifics in future interviews. Good luck!
