Non-GAAP adjusted EBITDA and non-GAAP adjusted EBITDA margin improvements relative to guidance were primarily driven by continued marketing spend and operating efficiency gains. Compared to last year, Non-GAAP adjusted EBITDA and non-GAAP adjusted EBITDA margin were lower primarily due to investments in the Varsity Tutors for Schools sales and government relations organizations and product development to drive innovation and support our continued growth.
