the two hours doesnt start until school does, which is 5 days. Usually im mining coal or mith, but if im trying to get levels, i powermine iron. I calculated how much xp i could get in 2 hours from powermining iron. Heres what i did. 3 iron rocks. It takes me 7 seconds to mine all 3 and drop all 3. By that time, the rock is respawned. 3 iron rocks X 35 xp each = 105 xp in 7 seconds. 105 xp divided by 7 seconds = 15 xp a second. 15 xp a second X 60 seconds in a minute = 900 xp a minute. 900 xp a minute X 60 minutes = 54,000 xp in an hour 54,000 xp in an hour X 2 Hours = 108,000 Therefore, everyday i can earn UP TO 108,000. I still have to worry about competition and randoms.
