Hi Isabella, Reaching B2 level in German – the minimum required for the Fachsprachprüfung (FSP) – typically takes around 600 to 750 study hours, according to the Foreign Service Institute (FSI). Here’s the source: https://www.fsi-language-courses.org/blog/fsi-language-difficulty/ For Approbation, two of the most widely accepted B2 exams are the Goethe-Zertifikat B2 (https://www.goethe.de/ins/de/en/prf/prf/gzb2.html) and telc Deutsch B2 (https://www.telc.net/en/language-examinations/certificate-exams/german/telc-german-b2/). Both are officially recognized across Germany and accepted by licensing authorities. You can take these exams at accredited language schools or Goethe-Instituts.
