Test server unlocking

Hello, its my first time logging onto the test server.

What do I have to do to unlock the high tiers?Do i have to grind it?

on world of tanks test server we used to have unlimited money and XP to instantly unlock everything

how does it work on war thunder test server?

You have to grind it but grinding is 5 times faster on the dev server. You make 5 times the RP and SL.
