Hi! So I'm no expert but a few of my friends are going on to be primary teachers! I think a degree is required and the easiest route to this is through A Levels. Really just do subjects that you enjoy and you can't go wrong since primary isn't specific enough for you have to do any specific courses! When you go for a degree, I think you either need to do an education undergrad or any undergrad and then a pgce but if you aren't even at the age of A Level yet then it's something you'll be able to find more info on in the future! Hope this helps 😊
