The college timings for the study completely depends on the time table.
Usually, in Sastra University Law College, the timings are between 8:45am to 5:15pm.
Depending upon the time table, some days your classes might start late like around 9:45am, some days they may end early amd the students might get free by 3pm.
There is approximately 1 free hour every day.
Hope this helps.
