Yes, you need to apply (again) for each new course. Please go to the home page of the online application system and login to your existing account. You can click on the 'Apply to another programme'-button to apply for another course.

When you apply for another course, you will have to upload a new motivation letter for that specific course.
It is not necessary to upload the other requested documents again (e.g. your cv, diploma, etc.), they are already in your application file.

Only if your CV in the system is older than 2 years, or you have new diplomas that are relevant for your study at KIT, please upload these documents in your application file!

On forehand we cannot give any information about the results of a new application. You will have to wait for the answer from the evaluation board. If you are admitted to the course you applied for, you will receive a new admission letter.
