I'm pretty skeptical about including past questions + solutions in your summary book. This will just make your summary harder to navigate, and what questions would you even include? If it's a challenging question that you did in the past, or couldn't do in the past, you should instead just make sure during revision time that you fully understand it and can do it again in the future without help. You don't want something super thick and unwieldy sitting on your table during the exam.
When I did methods, I just brought the textbook into my exam because I knew that I wasn't going to use it anyways. I didn't even really keep notes
throughout the year because that's just not how I learn maths. Instead of working on a summary, I spent all of my time doing as many practice exams as possible. I think this helped me far more than a summary would have.
But this is incredibly personal, so I'm not recommending you to not write anything up unless you also feel like writing notes doesn't help.
