So as Sven said, we have policies in place that discourage having students submit old work, due to it largely becoming irrelevant. For example, being at lesson 4, if you received feedback on lesson 1, then submitted your old box challenge, it wouldn't incorporate any of that feedback. We've had many students, as a result, who've made the difficult decision of going back to the beginning and actually doing the homework anew. It's never easy to decide to do that, though for them it has always been immensely beneficial, as they've come back with additional experience, but with the humility to take and apply the new feedback as intended within the course structure.

Either way, you are correct that the schedule you posted is the quickest one can receive feedback due to the 14-day-between-lesson-submission restriction (which again is there to encourage students to do the work after receiving a critique for the previous submission). There's one mistake though - lessons 3 and 4 cost 2 credits each.

This doesn't actually change your listed schedule though, because pledging at the $10 tier right off the bat would get you 3 credits (2 + 1 bonus for pledging at a higher tier when starting), so assuming you pledged at the beginning of a given month and submitted lesson 1 immediately, it'd look like this:

• Beginning of the 1st month, receive 3 credits

• Immediately submit lesson 1 (down to 2 credits)

• Halfway through 1st month, submit lesson 2 (down to 1 credit)

• Beginning of the 2nd month, receive 2 credits (3 credits total)

• Immediately submit lesson 2 (down to 2 credits)

• Halfway through 2nd month, submit lesson 3 (down to 0 credits)

• Beginning of the 3rd month, receive 2 credits (2 credits total)

• Immediately submit lesson 4 (down to 0 credits)

This stuff becomes somewhat less relevant if you end up going through the lessons as intended, rather than submitting old work.
