I need help with the following; I am learning how to write application in German and I was wondering if the sentence below is gramatically correct:
Zurzeit befinde ich mich im 3 Semester meines Studiums der Mathematik und in diesen 3 Semesters habe ich sowohl Teoretische als Angewandte Mathematik Kursen gemacht.
What I want to say is:
I am currently enrolled in 3rd Semester as an undergraduate in Mathematicss and during these three semesters I have taken courses in both Theoretical and Applied Mathematics.
Thank you for your feedback beforehand!
