hi!
i'm also in year 10 and in the same boat in terms of the lockdown and no spanish lessons.
i would encourage you to practice the things that you struggle in (you can find spanish texts for reading comprehension online, or past papers for ideas about writing questions).
it would also be beneficial to listen to a spanish podcast or watch a spanish netflix series or movie, which would help with your listening and speaking skills (as well as being relaxing and not too strenuous). i would recommend the duolingo spanish podcast which is specificallly made for language learners. for a series it would be best to watch something you're interested in - i watched brooklyn 99 episodes with spanish audio.
you should be able to find the aqa specification online, use this to look at grammar concepts that you should be studying at the moment and to recap the ones you have already studied.
lastly, recap vocab; quizlet is a good website for vocabulary because you can identify the ones that you frequently get wrong instead of repeating the ones you already know.
hope that helps, de nada!
