The eligibility criteria for MS differ in different universities. General eligibility criteria to study it in German University is as follows:
(a) High academics performance or records in undergraduate studies.
(b) If the course is taught in German, then proof of proficiency in the German Language. If the course is taught in English, then proof of proficiency in English by TOEFL or IELTS score.
(c) Some universities require GRE score
(d) With relevant work experience in the field of further study, chances of selection increases
(e) Demonstration of technical ability through project execution, participation in the technical symposium, conference, etc.
(f) Recommendations letters from internationally known faculty from where you have completed your graduation.

The basic difference between the two courses is the study orientation and pattern. M.Tech is a more detailed course with a vast curriculum. Under the M.Tech degree, one has to attend regular classes in order to gain knowledge about the subject. The subject under M.Tech is studied in detail in classes. This is probably because a lot of things in theoretical aspect are to be studied for which classroom course is essential. The project under this course is completed simultaneously along with the classes.
On the other hand, the MS course requires the least attendance in the classes. The course basically deals with the practical knowledge, self-study about the subject and the project. The students interact with the professors and attend those classes which are essential. They devote more time to their project in MS.
