Choosing between civil, mechanical, and aerospace engineering can be challenging, but the first two years of study are largely similar across these disciplines, allowing time for exploration. Engaging in engineering clubs, talking to professors, and job shadowing can provide valuable insights into each field. Aerospace engineering is typically the most demanding, requiring more specialized courses, while mechanical engineering offers a broader focus with significant overlap with aerospace. Civil engineering is often perceived as less rigorous, with fewer upper-level classes, but specialization can increase course requirements. Researching each program's curriculum and job prospects can further aid in making an informed decision.
