If I solve all level 5 problems in a week, it earns me 4120 points. I long thought this was the maximum possible one could earn within a week time. But apparently this is untrue, though I don't know how it's possible. The following person https://brilliant.org/profile/aisyah-sqvk0p/ managed to add a staggering 27185 lifetime points within the last week! Anyone that could give me an insight to how this is done? Are there secret problemsets I do not know of?
