If your progression through secondary school was or will be delayed or interrupted in any way, please check all that apply.

My answer is that I took several years gap.

It asks me to upload a document in response to that question. What should I upload amongst the following ( if not these then what? )?

a letter from my employer which would include my job as a call setup assistant or

a word document briefly describing my works

or sth else that would be better
