Lert: At this low amount of battles I would recommend spreading out your grinding, going up multiple lines in multiple nations. This game is not a race to tier 10, it's what happens while you play.   Spread your wings, see what nations and what lines fit your enjoyment and playstyle best, figure out your identity before dedicating yourself to one line.   There is no hurry. There is no grand prize waiting you at the end, and the higher up the tiers you go, the more experienced your opponents and the more powerful their tanks.   If you want to sit back and read up on game mechanics (which I wholeheartedly recommend!) there is a link below in my sig which leads to my collection of guides specifically written for newer players like yourself.   Welcome to WoT, hope to see you on the battlefield!
