Is an exam required for upgrading from C1 to B2 license?

[HadleyDella]

To upgrade from a C1 to a B2 license, you need to take exams. There are three exam subjects in total: Subject 1 (theoretical exam), Subject 2 (field driving skills test), and Subject 3 (road driving skills test). The exam subjects are divided into road traffic safety laws, regulations, and related knowledge test (Subject 1), field driving skills test (Subject 2), and road driving skills test (Subject 3). For first-time applicants of a motor vehicle driver's license or applicants adding permitted vehicle types, the vehicle management office should issue a driving skills test permit within three days after passing Subject 1. The driving skills test permit is valid for two years, and applicants must complete Subjects 2 and 3 within the validity period.
