Universities in the USA and Europe generally require a strong foundational background in science or engineering for admission into graduate programs, particularly for fields like nanotechnology. Individuals with a BS in business administration may find it challenging to transition into these programs without additional coursework. It is often necessary to complete undergraduate-level science and engineering courses before being eligible for graduate studies. Programs like Boston University's LEAP offer pathways for students to catch up on required coursework, but they can be costly and do not confer a bachelor's degree. Candidates with some engineering background, including coursework in mathematics, physics, and chemistry, may have a better chance of acceptance, though they will still need to address any gaps in their education. The discussion also highlights the importance of considering various global options for study, with a preference for English-speaking institutions in North America and Europe.
