Young Sheldon S04e01 Mpc Online

The episode picks up immediately following the Season 3 finale where Sheldon (Iain Armitage) graduated high school at age 11. He has been accepted into CalTech, but he is still a year away from starting college. He wants to spend his summer taking a summer-school physics course at East Texas Tech. However, Dr. Sturgis (Wallace Shawn) informs him that he cannot take the class because he already knows more than the course offers. Sheldon struggles with the realization that he may have "nothing to do" for the summer, leading to an existential crisis about his intellectual stagnation.
