FAQs
Is a Bachelor of Science in the USA worth the cost?
Yes – if chosen strategically and aligned with career goals.
Can I change my major in the USA?
Yes. Nearly 30–35% students change majors at least once.
Is US BSc better than UK BSc?
Depends on learning style. US offers more flexibility and exposure.
Is a 3-year degree from my home country enough to enter a US BS mid-way?
The “16-year rule” is the standard. Most US universities require 12 years of high school plus 4 years of undergraduate study. To transfer mid-way, you must undergo a WES (World Education Services) or EP (Educational Perspectives) evaluation. These services perform a credit-by-credit analysis to determine if your 3-year degree is functionally equivalent to the US credit system. Typically, a 3-year degree is evaluated as 90 credits, meaning you would need to complete at least one more year (30 credits) in the USA to earn your BS
Does the prestige of my specific major matter more than the university ranking?
In the STEM world, yes. A BS in Computer Science from San Jose State University (ranked lower globally) often has a higher ROI than a general degree from a top-20 Ivy because of its location in the heart of Silicon Valley and its deep industry partnerships with Cisco, Google, and Apple.
