Different schools and instructors use different cutoffs. The standard scale here uses A=93, A-=90, etc., which is the most common US convention. Some places use a strict 90/80/70 ten-point scale; some use plus/minus only at the top end. Always check your syllabus.

FAQ

Why do scales differ?+

Each school sets its own. Most US universities use 93/90 for A/A-, but high schools often use a strict 90/80/70 ten-point scale. UK degrees use a 4-tier classification: First, 2:1, 2:2, Third.
