Yes. Interests can add dimension even when they are not another achievement bullet.

The value is often in showing genuine curiosity, consistency, or personality rather than proving leadership again.

Photography could lead to a natural conversation about how you notice details, travel, or build a creative practice without forcing a consulting lesson.

Mention interests you can discuss enthusiastically and specifically rather than choosing one because it sounds impressive.

I would definitely avoid converting grades yourself. Too much room for the recruiter to wonder how you got the number.

I would ask one clarifying question only if it changes the decision. Too many can sound like you are avoiding a view.

The practical test for me is whether I can explain the reasoning in one sentence after the calculation.

I would rather have one strong example with clear ownership than three weaker examples with fancy titles.
