So you want to get better...
If you seriously want to improve your chess game, then you are in the right place. The tools that chess.com has put together for improving various areas of your game are priceless.
One of my favorite areas on chess.com is the "Tactics Trainer." If you are tired of your opponents hitting you with a one-two punch...get into the tactics trainer. I strongly recommend a minimum of three puzzles a day. It also helps to do them at the same time of the day.
If you haven't found this and other tools, choose "Learn" from the menu bar. Then choose "Tactics Trainer", it will eventually launch a separate window. You will get a separate rating just for tactics.
