Pursuing an undergraduate degree in Physics at 36 with plans for graduate studies in Electrical Engineering (EE) or Chemical Engineering (ChemE) is considered rational, as there are no age limits in science or engineering. However, prospective students should carefully review the admission requirements for their desired graduate programs, as many have specific undergraduate course prerequisites. Fulfilling these requirements may extend the timeline for graduation, potentially adding an extra year of study. Additionally, research experience is often a critical component for graduate school applications, and candidates should assess their qualifications in this area. For those aiming for a Ph.D., the process typically takes 5-7 years, with potential delays due to course requirements and the nature of research work, which can be unpredictable and time-consuming.
