Which are the best universities in USA for MS in Analytics, Big Data or Business Intelligence? How much GRE should I target?

Yes, to some extent. Both test quantitative reasoning and logical thinking. But GRE also includes Verbal and Analytical Writing sections. These sections are not part of dMAT exam to study in Germany.

Universities like TUM, RWTH Aachen, and KIT ask for GRE scores for select programs. Mainly in Engineering and Computer Science. Always check the exact programme page.

Just remember, objectives of dMAT and GRE exams are different.

No. The dMAT is just an APS verification requirement for Germany. It does not replace the GRE. If your target German university explicitly asks for a GRE score for admission eligibility, you must still take it.

Yes, GRE is still required as dMAT has not replaced it. dMAT is an aptitude test required for the APS documentation process, and GRE is a university admissions test. Both these exams differ in their purpose and the courses/documents they're used for.
