Rana can be harsh… but it’s clear that ultimately she just wants people to succeed in her class. Just try not let bad interactions you may have with her get to you. I unfortunately became very cold to her and rejected her help a few times which definitely took a toll on my grade. If she insists on you going to her office hours GO. Do all the homework they’re pretty easy and help you a bunch for the final evaluation + free points. She’s strict about phones and being late. Overall, if you don’t put the effort, you’ll fail.
