to make the most experience, which accelerates your crew training or tank upgrades, you can use this method.
- pay for a premium account when you plan to play often
- make sure you play your best when you get a 2x, 3x, or 5x bonus
- try to get the mose damage possible. experience is most earned by total damage
- have more higher tier tanks. they cause more damage, and earn more experience
- have more tanks. more tanks means that you get the 2x bonus on more tanks every day. for example, I currently have 21 tanks, all of which get a 2x bonus every day plus the premium
- make sure you have the best crew in the tanks when you run for the 2x bonus, if you share crew amon different tanks
- use premium rounds, especially when running for your 2x bonus.
- check 3 day specials, when WOT offers 2x experience for all battles, or with specific tanks
I don't know what my record is, but definitely had a game where I got 2,994 experience from 1 battle, where I won the 2x bonus and had premium. I think the tank was a T34.
