I am in year 11 and want to partake in computer science A level. My school does not have the course of Computer Science available but one of my teachers (who is familiar with computer science and A levels) suggested I learn languages in my free time and I would be able to do A level Computer Science.
I am relatively confident in JavaScript and am looking to familiarise myself with another language. I need to know how many languages I should learn and, if possible, which ones would be the most beneficial for me to learn.
