Germany

Instead of finding it is good or bad you check are you eligible for MBA. admission.

Dear Chandan, I will suggest you to refer to Financial Times Ranking for MS Management, you will find the comprehensive list. You need to then check the university websites for details. Admission process is online, check the websites for requirements, GMAT or GRE would be required apart from IELTS or TOEFL. Keep your academic transcripts and LORs ready too.
Best Wishes

Germany is good

Yes you can definitely do masters but before it all depends on your current qualification and current stream, course and certification , recognition etc.

You hv to compete gmat to pursue mba from abroad.

Not in Germany, but you can pursue 11th and 12th which are called associate degrees in Canada from a local community college or a junior college.

For Masters, IELTS score of 6.5 and higher is required. You need to retake the test. Your academic grades will also be evaluated in addition to IELTS for admissions.

There are no diploma courses in Germany as such. If you are interested for PG Diploma courses look for options in Canada, NZ and Australia.
