flashcards or memorising flashcards during y10 summer?

So, I've just completed creating my history Elizabeth flashcards today, and my sociology family flashcards are done too. Now, I'm contemplating how to best utilise my time during the summer. I'm torn between making flashcards for all the content I've covered in Year 10 or focusing on memorising and making flashcards, even though I might not be able to finish making all of my flashcards by September. I have concerns that simply memorising my current flashcards might be useless because the information might not stick well since there's so long until now and GCSEs and also the large number of cards are demotivating me from going through them all, especially for Elizabeth where there are 104 cards. On the other hand, if I review these flashcards consistently from now and throughout Year 11, the knowledge might stick better in the long run, but then I won't have all of my flashcards done when September starts. So should I just focus on making flashcards or making them and reviewing, despite the fact that I won't be able to have flashcards for all of Y10 content done?
