Chemistry gap year?

Hi all, i’m a student retaking chem due to extenuating circumstances on my gap year and I want to find extracurriculars that I could do for my PS, i plan to apply to RG unis for chemistry/chemical engineering. So far I’m just working normal customer service and volunteering, but what can I do ie research projects that help me have a more competitive application as most programmes are aimed at y12/y13?? thanks!
