I think you have to start from the start if you decide to go Patreon. The feedback you get is cumulative and often refers to previous issues. Self assessment or community assessment isn't as rigorous IMO. So Patreon is very much worth doing.
If you don't go that route then I would spend a few days refreshing your memory by doing some examples of previous exercises before restarting lesson 3.
Feel free to look at my official critiques if you want an idea of what you get for your money.
