I'm applying for master program in finance and the supervisor of my previous internship agreed to write me a recommendation letter but asked me to give him a template. Could you help on my draft?

the question is In which areas of development has the applicant progressed most in the time you've known them?

I believed Michael gained a lot of technical skills working with us. I was also impressed by his huge progress on how to manage different projects at the same time while keeping the best of his work quality.
