No, in the top right corner of your screen you will see three things
Three Gold Coins - represents the amount of gold you have (you can get 300 free by changing your password btw)
Three Silver Coins - represents silver you have
Gold Star - This is free experience which can be used for anything, ie researching new tanks, increasing crew stats, and researching modules (I would suggest saving it for researching modules as you unlock new tanks)
There are two types of experience; tank specific and free.
Free experience is earned every battle (I think it is like 5%, off the top of my head, of your total base experience earned during every battle) and can be spent on any tank you want.
Tank specific experience is what you earn during battle (it can be modified by using a premium account, x2 you get for your first win of the day in that tank, any other bonus you get on weekends x3 and x5 for really special occasions, and the special consumables you can win during events) and which can only be spent on that specific tank for modules or to research the next tank(s) in the tech tree. You can see this experience when you select your tank, it will display how much experience you have on that tank, you can also look when you select your tank and hit the research button.
** Once you have researched the next tank in the tech tree AND unlocked all the modules for your tank, that tank will become elited. Elited tanks earn experience just like normal tanks but you have the option to either continuing to build up experience that can be converted to free experience through the use of gold or you can dump that experience back into the crew.
If you dump it back into the crew it will go to the crew member with the lowest experience total. An example would be if you had a standard crew (Commander, Gunner, Driver, Radio Operator, and Loader) at the end of a battle you earned 1000 experience all the crew members would get that 1000 experience and the one with the lowest total would get an extra 1000 experience. Please note that if they all have the same experience total it will go to each crew member in order (Commander first battle, gunner second battle, driver third battle, etc.... etc....).
