Columbia University Science Honors Program ENTRANCE EXAMINATION

<p>50/50 ez math (i think)
~70/75 Science
9/15 Challenge Math (11 answered, 2 wrong so far) </p>

<p>Sophomore from Central NJ, how are my chances looking? </p>

<p>Oh and for what it’s worth, a kid in my school got in with perfect on math and almost perfect on science, but only answered 3/15 on the challenge. So have faith guys!</p>

<p>it appears they weight science pretty heavily…but its so hard!
i never learned earth science before…and that was like half the test. i knew almost nothing on the science section. im lucky if i got a 50/75.
how do you guys get such insane scores on science…</p>

<p>No, the cowboy one was simply 17.</p>

<p>50/50 on Easy Math
answered 44/75 on science, but to be safe I’m calculating 25/75 points.
9/14 answered on hard math, but I probably got 1-2 wrong including the red card blue card probability question.</p>

<p>Thank god, I got 17 as well.</p>

<p>Also, did people get these answers on the science portion? </p>

<p>Rh- and Rh+
Below 5 (for keq)
10 (for the distance problem with the 550 cycles and 1100 speed)</p>

<p>how was the cowboy one 17?</p>

<p>If you reflect the cabin across the river, you find that it is exactly 8 to the east and 15 north. By pythagorean theorem, you receive 17 as the answer.</p>

<p>me:
I was pretty sick during the test ;(
Math: 48-50/50(what was the answer to the H ant T question??? also, 1950 had the highest difference between peaks right??)
Science: LOL probably around 50/75
Challenge math: 13/15
How are my chances? they don’t look too great because of my science section…</p>

<p>I think the Red card question was 1/3. You can pick r/r, r/b, or b/r. Only r/r works. 2 was -b/c.
I think I got 46-47/50 on math.
Science was terrible. Counting 30/75 to be safe.
Challenge I know I got the cowboy wrong. Probably 6-7/15.
Im not getting in for sure lol.</p>

<p>The red card one was definitely two thirds. </p>

<p>You can pick RR (twice for each side), RB, or BR
Saying red card face up eliminates BR, so you have RR RR or RB so 2/3rds. </p>

<p>What was the one about Sue and Anne and the papers? I got 150. And what about the one with the 5 equations? a/2<x<4a, a/2<y<4a, etc.</p>

<p>I’m a sophomore in Long Island that hasn’t taken Physics yet.
50/50 easy math
probably between 65 to 60 out of 75 science
9/15 challenge math
What are my chances?</p>

<p>Sue and Anne was 150.
ugh i put 3/4 for the cards one.
i got E for the cowboy one. it was like root32 +root137</p>

<h1>2 was -b/c</h1>

<h1>1 was 2</h1>

<p>i got 3 numbers for the (n+i)^4
i guessed 116 for the race thing with runners ABC
WHAT WAS THE BASE R QUESTION??? IT WAS WORDED SO WIERDLY; I WAS SO MAD B/C I STUDIED HOW TO CONVERT BASES YESTERDAY UGH</p>

<p>For the red card didn’t it say the upper face had to be red AND the lower face had to be red? You don’t have 2 choices for RR. Either way it is red up red down. So, you have RR, RB, BR. Only RR works so 1/3</p>

<p>I said 12 for the bases one. Had no idea how to do it.</p>

<p>H and T question - H < T because nearest thousands means max 500 off</p>

<p>i remember every single challenge problem but not their numbers, sorry
ratio of squares = 2
ax^2 + bx + c = -b/c
integers for (N + i)^4 = 3 (-1, 0, 1)
hexagon side length = 4 sqrt(3)
the race with a beating b by 20, b beating c by 10, a beating c by 28 = 100
valves where a+b+c is 1 hr, a+c is 1.5, b+c is 2 = 1.2 hours
cowboy taking horse to river for water = 17
gravel road cutting circular grass = 30 pi - 9 sqrt(3)
coinciding hypotenuses on 30-60-90 triangles, area of intersection = 12 sqrt(3)
probability of picking r/r = 2/3
this card has false statements = 3
8% decrease means (x+10)% profit = 15% original profit
3 sheets and 1 sheet letters = 100 envelopes, 150 sheets
24 squared is 554 = base 12
a/2 < x < 2a, a/2 < y < 2a, x+a > y, y+a > x, x+y > a = 6 sided set</p>

<p>i’m about 99% sure on every one, correct me if wrong. thanks for contributors in this thread who helped me remember everything</p>

<p>sigh, looks like a rejection letter june 19-21. right in between SAT scores too. :(</p>

<p>@BasedGod2200 nahh people get in despite not doing THAT well on challenge math, but you’re not the only one alone freaking out. After I left my testing location, the International and Public Affairs Building, today, I heard people all saying, “I BOMBED THAT OMG.” Then I was asking around too, and not everyone answered a lot. I’m scared too though, lol. I skipped most of the physics stuff and some of the bio I forgot, but I got 2 other bio questions wrong though.<br>
@Everyone: Does the application, recommendation, or anything else have any influence?</p>

<p>ugh i hope. i did horrible on the challenge math doe.
and no, those things are basically useless. However, they do help if you are in a tie for the last few positions.</p>

<p>Yeah, lol. I’m not going to make assumptions about the answers to the challenge math though because a lot of people got different answers, so I’ll just play safe and not worry about it. Is there a curve for sophs or for people living distantly from the city?</p>

<p>some science questions:

  1. Resistor with the voltmeter and ammeter: was the answer “that the same amt of current flows through the voltmeter and ammeter”
  2. what was the answer to the electron config one? microscopic studies of carbon?
  3. the dripping water out of the cave one. i put that distilled water has no minerals
  4. why did scientists always change their classifcation systems?
  5. carbon burns was that oxidation?</p>
