You're looking at this in the wrong way. This isn't grade school where you're expected to pass a test, and everyone will be super disappointed in you if you don't. The homework submissions themselves are not tests. What you're doing is collecting a body of work that will help another identify whether you've understood the concepts covered in the lesson. If you haven't, then what you're doing wrong will be explained to you, and additional pages may be requested to allow you to demonstrate that you do now understand the concepts.

That's all it is. You're not being graded, nor are you being judged as a person. You're here to learn and understand concepts, and we're simply ensuring that this happens.

If you are dilligently following the instructions of the lesson then you are very likely to pass the review. Re-submitting happens when someone clearly failed to understand the lesson material and fails to avoid even the mistakes explained in the lesson.

And while re-submitting aint that bad (usually it's just one page or two you need to re-do, not the whole thing) the failure rate is very low for lesson 1 and the boxes exercises (under 10% I'd say). From lesson 2 onwards it gets more difficult (both in terms of difficulty of the exercises and because Uncomfortable does the official critique).

Just finish the exercises and submit the work. Someone will tell you where you need help and that should give you a better idea on what to do to improve. We are all our own worst critics.
