* Careful course selection: The student would need to find significant overlap in coursework between the two majors. This is more likely to work with closely related fields (e.g., Biology and Chemistry, or Computer Science and Mathematics).
* Heavy course load: The student would need to take a significantly higher number of credits per semester than the average student. This requires exceptional time management and academic ability.
* University approval: The university would need to approve the plan and ensure it meets all degree requirements for both majors. Many universities have rules against double majoring in unrelated fields within the standard four years.
* Summer classes: Taking summer courses would be almost essential to fit in the necessary credits.
In short, while theoretically possible, it's a very challenging undertaking that requires dedication, planning, and the cooperation of the university. Most students who want to study two subjects will choose to pursue a double major, which usually takes longer than four years, or focus on one degree and take electives in their secondary field of interest.
