Fastest way earn Core Tyria exp
An organized Silverwastes farm, tag as many events as you can.
Do Tequatl The Sunless world boss, that thing give massive exp if I remember correctly (also big karma)
And as above said, do Silverwastes organized RIBA map.

High Level Fractals earn you Core Tyria XP as well.
Depending on scale up to 600k XP per fractal.
I believe Dungeons give much XP as well. You will fill 3/4 of your XP bar by completing one dungeon path. Correct me if I am wrong since I haven’t followed this for a long time.
I haven’t checked the math in a while, but most of the incoming Exp for event/task based rewards are % of a level, scaled to the event level.
Open world events give 7% of a level based on the event level. So for lvl 80, thats easily 26k exp for a gold medal. Dungeons I believe give a whole level per Exp path completed. Fractals I’m unsure, but they do have multiple sub-events, including the boss fight. So with that in mind, map event trains are a strong source of Exp for practically no overhead on your part.
Though keep in mind that these rewards are based on % of levels, which caps at 80, but the mastery tracks operate on a vastly larger value scale. So an even doesn’t give you 7% of the Mastery track….. just 26k exp of the potentially 5 million exp needed for a high tier track.
