These two types of standards actually complement each other.

1. YK-levels
 The YKY-levels partly match with the levels of the Common European Framework of Reference for Languages (CEFR).

  ​CEFR fully applies to YKY language programmes, while for the rest, it complements YKDD.
  In YKY, we also letter them in Latin (not in Cyrillic) alphabet::

•  A 1-A2

•  B 1-B2

•  C 1-C2

2. YK deepening degrees (YKDD)
  YKDD terminology is more figurative, self-explanatory and explicit:

• TOE ~ A 1-2

    "Try out a little of everything / every YK-activity ";

• PAD ~ B 1-2

    "Pick and Dig";

• Dive ~ C 1-2

    "Dive” is figurative;
    It means to learn in as much depth as possible.
