I don't wanna make a serious plan. Just a plan for estimation.

• Easy 100
• Medium 100
• Hard 100 (optional)

When I cannot reach green even if I did Medium 100, I would do Hard 100.

Easy 100 (25%) Medium 100 (0%)

• 3 quizes each day it will take 25 days.
• 5 quizes each day it will take 15 days.
• 10 quizes each day it will take 7.25 days. (These are estimated without revising)

• 2 quizes each day it will take 50 days.

• 3 quizes each day it will take 33 days.

• 5 quizes each day it will take 20 days.

• 10 quizes each day it will take 10 days. (These are estimated without revising)

  3 Easy, and then 2 Midium => 75 days (2.5 month)
  5 Easy, and then 3 Midium => 45 days (1.5 month)
  

Today (07/27) ---(75 days later)---> 10/09

TODO: measure how long does 5 quizes take.
