Do the skills build on each other where they need to be done in order?
I got a subscription, but wasn’t super interested in the first one, so it’s still sitting in the box. Then the other boxes started showing up. I now have a full year’s worth and haven’t done a single one, because I feel like I should start with the one I’m least interested in.
They don’t… just do whichever one you are most interested in doing. Each box more or less stands alone (at least that is what I am observing from my kids assembly of them)
They use some similar ideas (a servo is still a servo in a different context), but they are totally independent of one another. Do the one you find most fun!
