Completing a bachelor's degree in physics in just two years at a U.S. university is highly improbable, even for someone with a strong self-study background. The main challenges include the structured nature of degree programs, which often require sequential courses and prerequisites that cannot be bypassed. Most institutions do not allow students to take an excessive number of credits per semester, making it difficult to fit all necessary classes into a two-year timeframe. Additionally, pursuing such an accelerated path could hinder future graduate school applications due to limited coursework and research experience. While some individuals with prior degrees or extensive credits might manage to complete a physics degree in about 2.5 to 3 years, attempting to do so in two years is generally viewed as unrealistic and potentially detrimental to the learning experience. The discussion also highlights the importance of careful planning and the potential for burnout when taking on a heavy course load.
