Guidance Needed Regarding FMS SOP

Hi everyone!
Could you please provide your guidance and share tips on FMS SOP? I'm finding it difficult to figure out how to approach it.

Also can i highlight my class 10th and 12th percentages as they are better than college cgpa.

Academics: 10th - 92% / 12th - 82% / UG CGPA - 7.8
Does this declining academic trend put me at a disadvantage?

Also, can I highlight my class 12 leadership experiences , since my college offered limited opportunities?
