Theoretical Foundations of Data Science I 🥑

DSC 40A, Spring 2023 at UC San Diego

🪑 Seating assignments for the final exam are now posted. Note that our final is in Center 115, not our regular classroom! Also, if at least 85% of the class fills out both the End of Quarter Survey and SETs (Student Evaluations of Teaching), we will add 0.5% of extra credit to everyone’s overall grade. The deadline to complete both surveys is Saturday, June 10 at 9AM.
