Hardwick College J Term & College Life

Can anyone tell me how Hartwick College’s J Term works? I saw in a video that you can graduate in 3 years if you do 3 J terms? Also, how is Hartwick College life on the weekends? Do kids go home or is there a lot to do on the weekends that keeps kids there? My D and I visited yesterday. She loved it. The campus was beautiful, people were friendly, kids seemed nice, and down to earth.
