If you’re asking, “Can I apply for a BTech at the University of Stuttgart after 12th grade?” — you must have a higher secondary qualification equivalent to the German Abitur, with strong marks in Mathematics, Physics, and core science subjects. Most bachelor’s engineering programs are taught in German, so you typically need German language proficiency such as TestDaF level 4 or DSH-2. Some programs may also ask for basic English proficiency (IELTS around 6.0–6.5). Academic transcripts, passport copy, CV, and online application submission are required.
