u wrote Bsc then MPhys?, you dont need to include GCSE results, dont need to include insight programme as a point only include it in your cover letter when applying for that specific company, it isnt recommended to have 2 separate sections for volunteering and work experience and add more detail to your points as a 1 line description doesnt add much. Choose 3-4 points which are most related to finance/leadership and add depth to them, add others in the interests section.
