Starting an undergraduate career in Mechanical Engineering involves significant changes and challenges. Key advice includes preparing for a rigorous study schedule, particularly from Thursday to Sunday, and establishing strong relationships with professors to enhance opportunities for research assistantships. Maintaining a high GPA, ideally aiming for a 4.0, is emphasized. While some students may experience drastic changes, others find the transition manageable, with workloads often comparable to high school but at a faster pace. Engaging in side projects and forming study groups can enhance learning and provide motivation. Overall, hard work, enthusiasm, and a supportive network are crucial for success in this new academic environment.
