How can I control surveys based on progress of each participant?
I need participants to take a unit of task a day.
A unit consists of 2-3 passages, 2-3 questions per a passage. It's basically reading comprehension task, daily training.
1) A participant should take one reading task (2-3 passages) a day.
2) The next day, the participant will take the next reading comprehension task.
This following task should be opened/displayed (the next day:optional) only when the previous task is done.
