Tutoring less advanced students can lead to a perceived decline in one's own understanding and confidence, particularly when the tutor feels compelled to simplify complex concepts. The tutor expresses frustration over their ability to absorb new material, feeling that they must "dumb down" the curriculum to match their tutees' comprehension levels. This process creates a sense of hypocrisy and diminishes their confidence in their own knowledge. The tutor resolves to maintain higher standards in their teaching, aiming to avoid compromising their own learning experience. Ultimately, the discussion highlights the challenges of balancing effective teaching with personal academic growth.
