Germany Master’s Application – Need Help (From Bangladesh)

I’m applying for a Master’s in Germany from Bangladesh and I’ve booked my appointment for July 31, 2024. I have a few questions about the admission application process:

• When can I expect to receive the document-related email?
• Which semester should I target (Winter or Summer)?
• I haven’t taken IELTS yet—can I still get an offer letter without it?
• When do Winter and Summer intakes usually start in Germany?

Would really appreciate any guidance or personal experience. Thanks!
