How long will it take me to get to B2 as an absolute beginner?

Each course level consists of two half levels. You need 8 weeks per half level with our semi-intensive courses, so 16 weeks per complete course level.

Here is an example:

A1.1. – 8 weeks

A1.2. – 8 weeks

A2.1. – 8 weeks

A2.2. – 8 weeks

Etc.
