Bloqueo de Mazos

Hola, acabo de acabar una oposicion y me gustaria saber si hay alguna manera de bloquear los mazos sin perder la informacion que tengo ya creada, gracias

You can open the deck, tap on the gear/cog, then choose Study Options. If you give that deck a separate options group, you can set the daily new cards/reviews to 0.

Alternatively, you can select all of the cards in the Browse screen, then use Actions>Suspend.
