My top tip for remembering dates is, grab a family member (mums are least likely to say no) and talk them thorugh your history curriculum. If when you're teaching them, you find big gaps in your knowledge then they will notice and ask you about it, and then you know where your thoughts aren't clear enough and you need to put in some extra work You also remember more of what you teach compared to just reading aloud, so it's a really good way to learn.
