Earn Medals and Win
The best way to rack up experience points is to earn medals and, of course, win the match. You’ll earn 500 experience points for a victory, and 250 points for just completing a match. However, you can also get points from earning medals, which are rewarded based on how well you perform and how you play your character. You can earn Bronze, Silver, and Gold medals.
However, do note that the medals do not stack, and your reward is based on the highest level of medal that you got. This means that if you earn two Bronze medals and one Gold medal, you’ll only get the experience points rewarded from the Gold, and nothing from the other two. Bronze medals will give you 50 points, Silver medals give you 100, and Gold medals give you 150.
You can earn medals by completing match objectives, and playing up your characters’ strengths. For instance, if you play as Mercy, your medals are rewarded based on how much HP you’ve helped your teammates to regain, and how many offensive assists you’ve gained by buffing them. In short, play your character well and make sure to keep track of your team’s objectives – you will be duly rewarded.
