College Scholastic Ability Test Exam 2021 is an ability test in South Korea. Eligibility is 10+2. Syllabus and pattern GK, general aptitude and relevant topics.
South Korea is readying 60 percent more testing rooms and 30 percent more personnel for the Dec. 3 nationwide college entrance exam, as the third wave of the coronavirus pandemic looms, the Education Ministry announced Wednesday.The (Common Admission Test) CAT is conducted by the IIMs every year for admissions in the 20 Indian Institutes of Managements and other prestigious B-Schools in the country. It will be a computer based test and conducted in 2 sessions on 26 th November 2017.

The minister said the number of those quarantined could rise in the run-up to the test, urging authorities to be fully prepared.
The country added 313 more coronavirus cases in 24 hours ending at midnight Tuesday, the highest daily increase since Aug. 29. Of them, 15 are students. A total of 87 schools have been closed due to the discovery of virus cases among staff or students.
The country will enter a special virus control period for two weeks from Thursday until Dec. 3, when some 493,433 college hopefuls sit the eight-hour marathon exam, better known as Suneung here.
“Greater danger could come if we do not take the right action at this point,” Yoo said. “Considering that the hike in social distancing shows its effect around a week or two later and there’s just two weeks left before Suneung, the Education Ministry and local education offices are getting prepared for all possibilities,” she added.
The capital Seoul, the surrounding Gyeonggi Province and other parts of the country are escalating their social distancing level from the current Level 1 to 1.5 from Thursday. Incheon will elevate its own social distancing to level 1.5 next Monday.
A week leading up to the exam, the ministry will order all high school classes to move online and minimize transmission risks among students. Each testing room will house up to 24 people, down from the usual 28, to ensure distancing among test takers, with plastic dividers installed on each desk.
Students confirmed to have the virus can take the Suneung in designated hospitals or government institutes. They will have to be admitted to the facilities where the test will be conducted three weeks prior to the exam.
The ministry has prepared 754 testing rooms at 113 different locations to allow as many as 3,800 quarantined students to take the exam.
A total of 33,000 testing centers have been prepared for regular test-takers, up 58 percent from 21,000 centers prepared for last year’s exam. Around 120,000 personnel will be dispatched to those sites to manage the test.
During the special virus control period starting Thursday, Yoo asked multi-use facilities to strengthen virus control measures in care of students while recommending cram schools and private institutes refrain from in-person classes for a week ahead of the Suneung date.
Yoo said the ministry would unveil the names and additional details of cram schools that report new COVID-19 cases during the special period. She asked everyone to strictly follow virus control measures for the two weeks in order for Korea to successfully execute the life-defining Suneung amid the pandemic.
“I ask people to refrain from cheering in groups in front of testing centers on the day of Suneung and just cheer from their hearts,” Yoo said. “Creating a safe testing environment is only possible if each of us helps out and reduces the spread of the virus in our community.”

I received an email suggesting today’s puzzle (email and problem slightly edited for presentation purposes):
I am a high school student in Korea. I greatly enjoy watching your YouTube channel.
I am writing to share with you a math problem from the Korean SAT, the CSAT (College Scholastic Ability Test).
This problem is from the math section of the 1997 CSAT, a test known to have harder questions than other years.
I am curious to know how you would solve it. Thank you in advance for your time.

Here is the problem:
Text-version:
The diagram illustrates a right circular cone-shaped mountain.
The diagram illustrates a right circular cone-shaped mountain.
If you build a shortest distance track for a siteseeing train around the mountain, in which the track starts at point A and ends up at point B, the track will first go uphill, but then it will go downhill.
What is the length of the downhill track? https://software-chicago.mystrikingly.com/blog/sugar-pop-slot.
There are four answer choices:
200/√19
300/√30
300/√91
400/√91
300/√30
300/√91
400/√91
Wow, even the problem is fairly challenging to understand.
This problem took me over 5 attempts to solve it, and I most definitely would not have solved it in a test setting. But I was extremely thrilled when I did figure it out.
So I suggest give this problem an honest effort before watching the video which has the solution.
Solution in text/graphics below.

*Note to original post: pretty much every time I said or wrote “circular arc” I meant to say or write “circular sector.” A “circular arc” is a portion of a circle’s circumference; a “circular sector” is the enclosed region between the arc and two radii. I was trying to avoid saying “circular segment” which is the enclosed region between the arc and a line segment between the endpoints of the radii.
You can see the term “circular sector” used correctly in the following videos:

Answer To HARD Korean Test Question
(This was transcribed quickly after I made the video–please let me know if there are any typos/errors and I will correct them, thanks).
The crucial first step is seeing the cone can “unwrap” into a circular sector. This is because the cone’s vertex is a fixed distance (the slant height of 60) from each point on the cone’s base.
This tranforms the problem from 3d into 2d. It also makes it easier to determine the shortest distance track between A and B.
I first solved the problem using coordinate geometry, which you can see in my notes on a Desmos graphing page. Opengl 2.0 driver windows 10.
But I felt that method was too complicated to expect of students on an exam. So I then found a trigonometric solution which I believe was intended. The solution proceeds in five steps.
1. Find the central angle of the circular sector.
Suneung Practice Test
2. Place points A and B on the circular sector.
3. Solve for the length of AB.
4. Identify the downhill portion of AB.
5. Solve for the downhill track length.
So let’s go over each step.
1. Find the central angle of the circular sector.
The length of the circular sector is the circumference of the cone’s base, which is 2πr = 2π(20) = 40π, where r is the radius of the cone’s base.
The circular sector’s radius is R = 60, the slant height of the cone. We can also express the arc length as its radius times the central angle, which is 60(θ). So we have:
40π = 60(θ)
θ = (40π)/60 = 2π/3
θ = (40π)/60 = 2π/3
2. Place points A and B on the circular sector.
5 dimes review. Point A can be placed on anywhere on the arc, as those points correspond to the cone’s base. It is helpful to place A on a corner, so that we can place point B on the opposite radius of the arc to correspond to a track around the cone. Point B is 10 units from the base and 50 units from the vertex, so we place it accordingly on the circular sector.
Now we can find the shortest path between A and B quite simply: it is the straight line between the two points! This creates a triangle with segments from A to the vertex, B to the vertex, and AB.
3. Solve for the length of AB.
We can now solve for AB using the law of cosines, as we have a triangle with sides 50, 60, and an angle in between of (2π)/3.
AB2 = 602 + 502 – 2(60)(50) cos (2π/3)
AB2 = 9100
AB = 10√(91)
4. Identify the downhill portion of AB. Jungle adventures free.
It is given in the problem the line AB first goes uphill (increasing distance from the base/decreasing distance from the vertex), and then downhill (decreasing distance from the base/increasing distance from the vertex).
(If you want to verify this is true, you can see my Desmos graphing page where the derivative of the distance shows the track follows exactly this pattern).
Between the uphill and downhill portion is a single point on AB that is closest to the cone’s vertex. The line between this point and the cone’s vertex will be perpendicular to AB, so we form two right triangles for the downhill and uphill portions.
5. Solve for the downhill track length.
Let x be the downhill length, so then AB – x = 10√(91) – x is the uphill length. Let h be the distance from the cone’s vertex to AB. Now we can use the Pythagorean Theorem for the two right triangles to get:
(10√(91) – x)2 + h2 = 602
x2 + h2 = 502
Now here’s a neat trick: subtract the second equation from the first. Then the x2 terms and h2 terms will cancel. So we get:
9100 – 2(10√(91))x = 602 – 502
2(10√(91))x = 8000
x = 400/√(91)
So that’s the answer! This was the 4th answer choice of 400/√(91).

What a remarkable question this was! I could not imagine solving this in the time constraints of a test. But it was fun to solve, and the problem depends on so many different mathematical concepts!
