Hi Aimee, and welcome to the forum! I’m tagging @aran for you as he is the best one to advise you. But I also want to say that you can do the lessons in whatever way works best for you. You don’t have to do the whole thing in one go - if ten minute chunks work better for you, that’s fine. And you can use the pause button as much as you need to, if you find that helpful. The standard advice is not to repeat the lessons many times before moving on, but I know that changes for lower working memory, so I’m sure Aran will be along to advise.
We’re a friendly bunch here, happy to help with questions and support, so stop by anytime!
