Could you please check my sentences for grammar mistakes and if I used vocabulary correctly?

A complacent smile is a permanent resident on his face, yet he underachieves in many of his assignments. A noticeable distance stretches between his verbal comments and written work. His comments brim with insightful observations; his written assignmetns reflect his lack of self-discipline, work ethics, and intrinsic motivation. Doubtless, the discrapancy between his capabilities and achievements attests to the fact that personal attributes mentioned in the second half of the penultimate sentence play as a significant role as having potential in achieving.

Thank you very much for your help

Hi,

I've suggested some changes.

Personally, if I were a teacher writing this about a student, I'd avoid personal physical comments, eg about his smile, and I'd avoid references to his character. I'd just comment on his actual work.

Best wishes, Clive

Doubtless, the discrepancy between his capabilities and achievements is due to a significant extent to these personal failings.

mentioned in the second half of the penultimate sentence = not necessary and sounds awful.

I am just trying to find the best words to describe what I observe and I write for myself. The above sentences were inspired by a discussion with an acquaintance of mine who is convinced that her son deserves to get straight A's and fails, or does not want, to see that self-discipline and effort are as importand as having potential.

Thank you

Hope
