I think your friends might mean that a uni would require evidence of previous study. As suggested OU modules are a good way, you can study from home. Alternatively to OU is an access course, does what it says on the tin, gives you access to university. You can either go to college or online via a distance learning If you are in Scotland check out swap access to he courses, if not check your local college websites to see what they do. There are many different access courses depending on what you want to study at uni, for me it was access to social sciences which got me onto a history and philosophy degree. I think there are specific access courses for computer science, but am not sure. Before you sign up to anything, remember to contact any uni you are interested in to see what they would require from you to be accepted and what courses they would accept. Personally I chose to go full-time for my access, on my course many others also worked part time and managed fine. Be sure to check out what benefits you would be entitled to as well as what funding the college offers (in Scotland this differed per college despite them all being a swap access course). Also, check out the advanced learner loan, this would pay for your access course (distance learning as well as college) in Scotland the loan is written off if you move onto uni. There are many on here working full-time and doing distance learning as well that will be able to tell you more about that route 😊. I will say I have no regrets, I am 37 and in first year of uni and love it, it has been the best decision I made.
