Hi ! Actually I did my Biology and Chemistry AS Level after my degree! The reason why is because I wanted to learn more about science :). I regretted not doing those subjects when I was in school. I learned a lot and enjoyed studying them. So like most people, I completed 3 A levels (psychology, classical civilisation and politics) and 1 AS level (history) in 2 years. How did I stay motivated? Well balance is key. Work hard, and find the time to relax as well 🙂 I hope that helps.
