Hi
i got admission for tum mspe.
but i have 2 years experience in distribution switch gear equipment manufacturing field.
In TUM course structure, i believe only 2 modules are there related to my current experience field.
But TUM offers a good course structure in Renewable, which i believe is the future. If i switch now, without sticking to my current experienced field, will it affect me in the future ( getting a job and all).
BTU Cottbus course structure is more related to my current working field. So can anyone suggest which college to select.
Also can anyone tell me a little reg btu Cottbus. its location, part time job availability, living expenses, college ranking, etc.
Thanks in Advance
