1. The "Average of Averages" Sin

The Mistake: Adding up your GPA from Semester 1, Semester 2, and Semester 3, then dividing by 3.

Why it's wrong: This only works if every semester has the exact same number of credits. If Sem 1 was 12 credits and Sem 2 was 18 credits, Sem 2 accounts for 60% of the weight.

2. Ignoring "Pass/Fail" Credits

The Mistake: Including "Pass" (P) grades in the credit count for division.

Why it's wrong: "Pass" creates credits earned but usually carries 0.0 GPA points and should be excluded from the GPA denominator. Including them dilutes your GPA artificially.

3. Mixing Scales

The Mistake: "I got a 7/10 in Physics (India study abroad) and a 3.0/4.0 in Math. So average is roughly 3.5."

Why it's wrong: You cannot mix currencies without an exchange rate. You must convert everything to a single base scale (usually 4.0) before averaging.

4. The Rounding Trap

The Mistake: "I have a 3.45, so that rounds to a 3.5, which is basically an A-."

Why it's wrong: Computer systems truncate. A 2.99 is not a 3.00 for scholarship cutoffs. Never rely on rounding to save you.

5. Foregetting Labs and 1-Credit Wonders

The Mistake: "It's just a 1-credit lab, getting a C doesn't matter."

Why it's wrong: While small, they add up. Three 1-credit Cs have the same drag effect as one 3-credit C. They are the "silent killers" of a 4.0 transcript.
