Some tips:
-Play the mode you enjoy, for example just because Realistic gives more RP doesn't mean it's the best option for you
-Research vehicles one rank higher if you don't have a premium vehicle, as any higher there will be research inefficiency (for example, don't use a rank II vehicle to research a rank IV)
-Use vehicles you enjoy
-Stay in the battle as long as you can, and try to win as winning a battle gives much more research points
-Spade vehicles. Each tier you unlock in the modification window gives you research points towards the vehicle you're researching. Bonus amounts can be seen in the modification window.
