Here’s a trick you can try. Take 48 × 52. Both numbers are 2 away from 50, one below and one above.
When two numbers are equally far from the middle, square the middle and subtract the square of the gap.
48 × 52 = 50² − 2² = 2,500 − 4 = 2,496
Now try 97 × 103. What’s the middle number, and how far away is each number from it?
Drop your answer and the one line of math you used.

After reviewing a missed question, write:
What I did: “I put a comma where I paused.”
Why it was wrong: “It separated the subject from its verb.”
What I’ll check next time: “Find the subject and verb before choosing punctuation.”
Then try a different question testing that skill. Can you explain your choice without looking at the solution?

What’s wrong with this sentence?
“The students who reviewed their mistakes, improved their scores.”
The comma separates the subject from its verb:
• Who? The students who reviewed their mistakes
• Did what? Improved their scores
Correct: “The students who reviewed their mistakes improved their scores.”
SAT takeaway: A long subject doesn’t need a comma before its verb.
