Hey I'm a grade 12 student from India (graduating in 2027). I'm planning to study a Bachelors of Science in International Physics Study Programme (IPSP) in Universität Leipzig (2027-30). I'm required to attend a Studienkolleg but I'm really confused about a lot of stuff and mailing the University themselves has been unfruitful.

1. Am I required to come to Germany and enrol into a Studienkolleg in-person with an entrance test?
2. I have no knowledge of German, will that still let me enrol into a Studienkolleg?
