Should I prefer a broad engineering degree if I want to keep career options open?

Not necessarily. A broad engineering program may make it easier to explore different fields and choose a specialization as your interests develop. However, a more focused program may provide greater depth in a particular field, including related laboratory or practical work. Consider whether you can try the areas that interest you and gain the knowledge and skills relevant to your possible goals, then choose the curriculum that fits your interests and preferred way of learning.
