Yale University's happiest course is giving people yet another reason to smile. After breaking registration records, "Psychology and the Good Life" has been repurposed into a free online course anyone can take, Quartz reports.

Psychology professor Laurie Santos debuted the class in the 2018 spring semester, and it's officially the most popular course in the university's 317-year history. About 1200 students, or a quarter of Yale's undergraduate student body, are currently enrolled. Now that a free version of the course has launched on Coursera, the curriculum is about to reach even more learners.

The online "Science of Well-Being" class is led by Santos from her home. Throughout the course, students will learn about happiness from a psychological perspective, including misconceptions about happiness and activities that have been proven to boost life satisfaction. "The purpose of the course is to not only learn what psychological research says about what makes us happy but also to put those strategies into practice," the course description reads.

Each section comes with readings, video lessons, and a quiz, as well as the chance to connect and brainstorm with classmates. After passing the assignments, students come away from the six-week course with a certificate and hopefully a broader understanding of the factors that contribute to a happy life. You can visit the course page over at Coursera to enroll.
