What is the equivalent level of B1 in the French Delf exam? If you go to France to study at university, what is the minimum level of Delf you need to achieve? Is it necessary to pass the delf exam?

B1 is equivalent to 500-600 hours of French learning

The requirements vary depending on the major. A2-B1 for science and engineering is OK, but if it is business, the requirement is B2-C1 , and it also depends on which level you are applying for. L1 and L2 have lower requirements than L3 and M. Applying for majors is difficult, and some ecole require interviews.

Generally speaking, you must have a DELF B2 diploma to apply for the license level (undergraduate level) of a French public university, and you must have a C1 level to apply for a master's degree (graduate level)

Many schools also TCF and TEF are recognized, so delf scores are not required
