Hi Robert,
I have reviewed lessons from day 1 several times over the years. For one thing, they are revised every so often.

Reviewing depends on what you feel comfortable in having absorbed the training or needing to look at certain principals and info again.

Best wishes in re-starting your adventure at Wealthy affiliate.

Part of the learning process here is knowing how your site is set up and how to maintain it. I don't know if I personally would want to go that route. I have heard there are people who will do it for you. But for now, why don't you keep up the training. if you are finding difficult and it isn't clicking for you then review your lessons.
On the lessons page, type your question in the box at the top of the page and it will come up with the lesson you need to review. Don't throw in the towel yet.
I was totally frustrated and lost at about 1.5 months into it. But I didn't quit and suddenly it started to make sense.
