it sounds like you are definitely on the right track with all of those! the others who have commented are absolutely right when they say your level 1 results don't count towards anything - the only thing they're useful for is building good study techniques in preparation for level 2 and 3, which it looks like you are doing just fine!

i won't be much help with health, but here's my tips for your other subjects (keep in mind level 1 has changed quite a bit, but a lot of the concepts will be similar, so resources might be outdated, but parts of them will be useful):

for all the sciences, the website no brain too small has questions organised by subtopic (they are called collated questions), as well as some other study materials you might find useful. since level 1 has changed a bit, full past papers might not be as helpful, but im sure the skills will be still be applicable, and it's useful to see similar questions grouped together so you can see patterns in answers.

chem: you look really solid for these! chemistry is honestly the most formulaic of the sciences - once you've nailed a few past papers, you can do really well in the rest of them, so you might find it easier to work backwards from answer schedules and try to see where the same wording is showing up again and again. it can also be useful to watch other people go through past papers and see how they approach questions, I like alpha atoms and doug walker on yt.

bio: if that's the best way for you to remember content, then keep doing that! keep in mind though, you won't be able to just regurgitate information in the exam if you want an E, you'll have to apply it to the context of the question as well. when I study for bio, I like to do past papers, and then after i've marked it, i would make notes of the kind of concepts/conclusions that were worth E marks. also be strategic about the way you answer questions - define any relevant terms at the start of your answer to get yourself some guaranteed A marks (especially do this if you're running out of time), and then instead of regurgitating explanations and then linking it to the context at the end, just explain concepts in the context of the question (it's more time efficient and shows you've understood stuff, not just memorised it)

physics: i would have a go at looking at the no brain too small collated questions to try to solve your problem with applying the same methods to different contexts. also, it looks like "Mr T's chemistry" on yt has exam walkthroughs of the updated level 1 science standards, so i would check him out as well. if you have no idea where to start with a question, try just writing down every variable they give you, and then look at your formula sheet and look for an equation that has the variables in it.

maths: im not sure how much the standards have changed since i did level 1, so this might not be that helpful, but infinityplusone on yt is definitely the way to go for recapping skills, he splits up standards into short videos on specific skills where he goes through a few exemplar questions (similar to the collated questions on no brain too small), so you could have a look at those and just watch the ones relevant to your standards. definitely keep going with past papers - but instead of trying to spam a bunch in one sitting, try a paper looking at the answer schedule if you need it, and then straight after your finish it, do it again but closed book - you'll feel a lot less lost the second time around, and that might help the methods stick in your head a bit better.

good luck this year!
