ECON10A . 6 Months Ago

Lets just say I don't know how the econ department scored her. Smart, caring, inspirational. If even half of the professor actually cared about their students or taught like her we'd be top in the nation.

ECON10A . 6 Months Ago

TAKE BREE. She's literally the ONLY REASON I passed the class.Everyone knows 10A is tough. Yes you have to study hard, and yes you have to put in the work or you are not going to pass the class. She's not easy but but makes the class bearable. She really cares for everyone one of her students. The best professor at UCSB. Go to her OH!!

ECON10A . 6 Months Ago

Professor Lang is a kind and approachable professor who makes even the most difficult topics relatively easier. I still recommend attending the lecture and CLAS. The multiple choice exams were slightly different than previous exams used for practice (more math heavy) but is manageable. The final included both multiple-choice and written.

ECON10A . 6 Months Ago

I took 10A in fall as a transfer and did not get the grade i needed, retook it with Prof Lang and thank god i did. Finally got in. Her midterms are much more understandable and she'll hint what she's gonna ask on the exams. I got a 9/10 and a 7/10 on the midterms. Final was def much harder. The grading for this class is all exams. Study HARD!

ECON10A . 8 Months Ago

Great professor, genuinely cares about students. The course itself is just hard but she tries her best to help and has lots of resources available.
