Yes.

As a new player, don't expect to do well. Just try to grab the basic rewards at least, by running your strongest team until you have a total of 110m damage done. Also, you can try getting a high Total Score to compete against other player by getting the best score you can from each element. Again, do not expect to do particularly well in this, but that's the best way to get Guild Medals, which are used for highly valuable Eidolon bricks.
