<p>does anyone know anything about the professors karras for PE 100 and d'abrera for stats 2? i have read reviews on ratemyprofessor and courserank but they seem to be giving mixed feelings. also...does anyone know who teaches ias 106 (microecon)? it still says staff on the online schedule...</p>

<p>thank you!</p>
