If you want only to learn german and it doesn’t really matter for your uni applications, maybe consider taking german sl as a 7th subject.. i did that with french because i only wanted to learn the language, it wasn’t bc any uni requieres that subject. Your 7th subject doesnt go into your gpa, you just have to pass it with 3 on finals. At the beginning of the year, i was going to hl classes of french as well because i really wanted to improve my french and since we’ve got a great professor, I actually started speaking and communicating in french and i amazed myself lol (i mean we only spoke french in classes and had really interesting discussions) so i encourage you to take it as a 7th subject bc you don’t have to work hard for a 3.. i only cooperated in classes, didn’t study and got 6 and a 5 from simulations of paper 1 and 2 and my french was reeallly bad before. So if u have a subject that interests you along those that u have chosen and its maybe more important for uni or what u wanna study, take that subject and take german sl as the 7th one. Ik a loooot of people discourage you to take 7th subject but i think in that example it might be a good idea bc it doesn’t ruin your gpa and i think its easy to get the passing grade in case you are busy with the other subjects. Good luch with physics and math hl tho!!
