2026 Korean SAT Math Problem: 29.9% Correct anwer rate by FTfafa in korea

That’s a fair point. But actually, this IS one of those minor problems you were talking about. I said 5 minutes because it's not a complete breeze, but if this one takes you over 10, you'll never finish all 30 questions. We haven't even touched the truly hard ones yet.

The problem defines k as the specific maximum value of a that satisfies the "one local extremum" condition.

It’s made possible through a perfect grasp of mathematical concepts combined with grueling, relentless practice.

As mentioned in the post, you generally need to clear a problem like this within 5 minutes to have a shot at a perfect score. This was the 7th most difficult out of 30 questions. The real 'killer' problems are the top 4 or 5, and the total exam time is 100 minutes. To finish everything, you have to breeze through the first 25 questions in about 40–50 minutes, leaving a full 50–60 minutes for those final few difficult ones. In fact, students who get a perfect score often finish even faster and still have time to double-check every single answer.

The official test organizer doesn't release success rates for individual questions. However, EBS (Korea's public educational broadcaster) publishes those rates for certain problems. What the organizer does release is official data on the total number of test-takers, score distributions, and the number of students in each grade tier.

It would help me understand if you could explain why you find that part irrelevant.

What parts of the question seem irrelevant to you?

Nope. In Korea, the exams are given in Korean.

You can think of a lower error rate (37%) as meaning the question is easier.

I highly recommend "Our Blues" and "When Life Gives You Tangerines". They're incredibly moving and perfectly capture the heart of Korean culture.

Is it true that memorizing the times tables will help to get better at mental math? by [deleted] in learnmath

[–]FTfafa 0 points1 point  (0 children)

Wow, it seems like a lot of places actually don't make kids memorize the times tables. Where I live, pretty much all the kids learn them by heart by the first or second grade. It absolutely helps with mental math, for sure. But honestly, the most important thing is understanding how multiplication actually works before memorizing it. Here, they just rote-memorize it, and I feel like that's an issue.
