How is the quadrantal rule applied to VFR flights in Hungary?
Since the question is about Hungary, the answer will be in Hungary's AIP.

ENR 1.2 says:


  2.6. VFR flights in level cruising flight, when operated above 3 500 FT (1 050 M) MSL, shall be conducted at a level appropriate to the track specified in the table of cruising levels (ENR 1.7 para 3.).


(Emphasis mine.)

And by referencing that table (PDF) in ENR 1.7, it becomes clear Hungary uses a semicircular/hemispheric, and not a quadrantal rule.

The pilot's starboard drift will make their actual track 355 + 8 = 003°. VFR flights use the IFR rule + 500 (see below), so for this "eastbound" flight the pilot should fly odd + 500, an example would be FL 55.
