advice for a difficult TA

<p>All my son’s science lab course experience at UVA is littered with stories like that OP. It is why the internet is filled with stories of students leaving the stem fields in droves. But the administrators in charge cannot figure out why? I guess they think students love getting grades that they do not feel are indicative of their understanding of the material but rather based on unfairly graded labs or a ranking system that pits one student against another. Hands down the reason my son has ZERO intention of using his science degree from UVA in the field upon graduation. The lab system is fundamental flawed at UVA.</p>
