* FSc (Intermediate of Science) is a two-year intermediate program typically pursued after high school (O Levels or equivalent) in Pakistan. It's a pre-university qualification focusing on science subjects.
* A-Level (Advanced Level) GCSEs are qualifications taken by students in the UK and some other countries. GCSEs (General Certificate of Secondary Education) are typically taken at age 16, while A-Levels are taken at age 18, after two years of study. A-Levels are more advanced than GCSEs and are often considered equivalent to the first year of university.
In short, an FSc is roughly comparable to the *first year* of A-Levels, not to a GCSE itself. A-Levels are at a significantly higher level than GCSEs. There is no direct equivalence.
