I have heaps of experience. Ask me what you need help with.

Erm... don't be spy until you know how the game works.
Everything else... just play and ignore the people spitting on your corpse repeatedly. You'll get better with time, just like anything else.

But seriously, you should start off with a class like soldier and work your way to the other classes once you start getting used to it.

Spy main here, ask away.




Master stock weapons first.

You may always play the tutorial first. In addition, guides, as well as practice, may also aid you with the basics of the classes & other matters.

On another note, if you choose to play as the Sniper, do try to move to a different location after killing a few enemies. I do believe that it may help you avoid any enemies whom intend to kill you. Should such an occurrence potentially happen, however.

I'll help you with any class. Just state the class.

Play the tutorials first

I've played a lot of Demoman and Medic, I could provide some tips.

You could download this bot mod if you want to practice on every map with waypoints that isn't just the use of nav_generate.

The only situation in which you can win is not playing the game.

Now this one's not helping at all.
What's the problem tho

Kill the medic first, not the overhealed heavy.
As soldier, aim at the feet, not the chest.
Never stop moving.
Listen for uncloaking and shooting.
Don't stab and sap if the sentry is facing you.
