A good letter of recommendation should not provide colleges with?

A good letter of recommendation should not provide colleges with generic praise that lacks specific examples of the student's achievements, character, and potential. It should avoid vague statements and instead focus on concrete instances that highlight the student's strengths and contributions. Additionally, it should not include irrelevant information or personal anecdotes that do not pertain to the student's academic or extracurricular performance. Finally, it should refrain from overly critical or negative comments that could undermine the student's application.
