im trying to pick japanese back up after leaving it for 10 months, is there any way i can adjust renshuu so it fits my now lower skill level and not my previous skill and knowledge? or do i have to just make a new account...
Do nothing. Let Renshuu do its work automatically. The stuff you don't remember you'll get wrong and mastery will be adjusted down. The stuff you remember you'll get right, and the mastery will go up. Within a short amount of time you'll be quizzed according to what you actually remember.
Middle Option:
Perform manual mastery adjustment. Go in to the schedules tinker mode and adjust the mastery levels manually to where you think they should be
Nuclear option:
Go into User settings -> My Info -> I want to reset my account
