is masters program in tu munich is hard to get ?
It is not that difficult if you are good in Time Management and punctual from Day 1.
Maintain your CGPA. Anything above 8.5 is good for them but i would suggest you to go for 9 or 9+
Just focus on your GRE and please try to learn German at least basic German. Most of the courses here are taught in English but still if you know German then it will be a boon for you.
Maintain at least 2 LOR's, a solid LOR's i.e from the people recognized on a International level.
