# Theoretical Foundations of Data Science I π₯

DSC 40A, Spring 2023 at UC San Diego

πͺ 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 everyoneβs overall grade. The deadline to complete both surveys is **Saturday, June 10 at 9AM**.
