Can you get an A pass in gcse foundation science?

Yes, you can get an A grade (or a grade 7 or 8 depending on the grading system used) on the GCSE Foundation tier in science. However, it's important to understand that an A grade at Foundation tier is generally considered a lower achievement than an A grade at Higher tier. The Higher tier covers a more challenging and extensive syllabus. So while an A is achievable on Foundation, it represents a different level of attainment than an A at Higher.
