Columbia University Science Honors Program ENTRANCE EXAMINATION

They encourage you not to guess because there is a penalty is you get one wrong, whereas you don’t lose points if you leave it blank. Better for them to see you got the ones you answered all right, than you guessing and getting a lot wrong and completely ruining any chance you had of getting in. But you are right, if you are a good guesser and can get lucky, they really have no way of knowing I guess.

Does anyone wanna go over the challenge questions? I answered 9 and skipped 6. I believe I got them all right.

The science was very vague and as a freshman, I hadn’t taken physics yet. I probably got:

Easy math: 49-50
Science: 60-65
Challenge-11 (I skipped 3 and got one wrong)

Hopefully I get in with these scores and the curve this year is probably gonna be a little high cause the challenge tripped up a lot of people

@mStabile20 What did you get for the base r problem? I got 8.

Was the ratio between the areas of the two squares 2?

@scietywi do you remember the actual question and the info it gave? I believe I got 12 but I could be thinking of the wrong one. All I remember is that whenI plugged in my answer, it was the only one that worked.
Did you get 488 for the square question? Did you get E for the automobile question?

I took the test yesterday and considering I am a freshman who didn’t know how to prepare for it and have never taken chemistry or physics, I think I did pretty well

36 on math ( I only answered 36 and I believe I got all 36/36 right)(I really didn’t manage my time at all for some reason, I guess I thought 50 minutes was longer)
41 on science ( The only ones I didn’t answer were physics and chemistry I believe I got 41/41)
9 on challenge ( I believe I got all 9 I answered correct and I skipped the other 6 because I didn’t know how to do them)

I know I skipped a couple because I didn’t want to risk any penalties but I got all the ones I answered right, do I have a chance at getting in?

@mStabile20 It was 1100 mu (I think) and 440 mu, and gives you a change of 340mu. I may have mixed up some numbers. I honestly didnt really know how it worked, so a full explanation would tremendously help :slight_smile:

Yes I got 488 for the square (cube) question since 8^3=512 and 1000-512=488.
Frankly I don’t remember what the automobile question was. Refresh me there please

@sidthekid123 Yes it was 2.

I thought I got that wrong. Phew. I think the automobile question was the one with going a/6 feet per second in r seconds and how many yards it would go in 3 minutes? Not 100% sure. Got that one wrong cause i forgot to divide by 3 xD

the ratio was 1/2 right? because when i set the side length of Square 1 to 1, a=1. Because the length was 1, the diagonal (also the side of square 2) was radical 2, and radical 2 squared is 2, leaving a ratio of 1/2. If anybody sees this and notices a problem, please correct me. and for the answer to the automobile question, i got 10a/r which I believe was E

I thought that the side of square 1 was the diagonal of square 2 so if the side length of square 1 is 1 then the side length of square 2 is radical2/2, leaving a ratio of 2/1.

@nStabile20 I think you’re right! Was the automobile question part of 1-3? Because I got E for the first three answers lolol :slight_smile:

@scietywi I got 12 for the base one and yea I also had e e e

So did I! And what did you get for the base one, I got 12 I think. It was something like 1000 mu, 340 mu, what is the base.

well did it ask for the ratio of s1 to s2 or s2 to s1?

@nStabile20 the ratio was s1 to s2 and i got 8 for the base.

How did you get 8?

@sidthekid123 I got 8 too! I factored the bases out into a polynomial and got an (x-8) term and others. But in the answer choices, 8 was the only one that worked so I picked that lol. I may be wrong though. Can you explain how you came to your solution? Thanks!

@scietywi Thats what I did too. But then I used base 8 and converted the numbers they gave into base 10 and all the numbers added up perfectly. And do you remember what the exact question was for the squares? Cause I was pretty sure that the side of s1 was the diagonal of s2 but idk

what number problem was the base one?
