So we have a test during Frosh week. This is all stuff we were supposed to know in High School. Only problem is, there are no answers. If you have some time, and are kind enough, maybe you could tease your brain while helping me practice. 🙂 The physics and bio question need the most help. I'm just rusty on Calculus, and I should ok with Chem... but I have NO CompSci experience whatsoever. Any help on that too is good.

The link is here: http://utics.skule.ca/Sample_questions.pdf

Notice how they are Sample Questions, not part of any project or homework. Just looking for some good help and review from a great community. 🙂

you're kidding me right?

not that many people have taken comp sci...i didn't really look at the questins.

but FVCK, that sucks, freshman week : P, after not doing anything for 3months, ahha SUCKS for you. : ).

does this thing actually count for anything? I can't believe they make you do this...never heard of that before...math placement and language placement is where it's at.

There is no UofT Internal Controls and Standards.

Yes there is. It's from skule.ca, UT's Engineering site. Regardless I still have this test next next Wednesday, from UTICS. Unforuntately I don't want it to exist either, but...

Here's a link for the non-believers. http://utics.skule.ca/main.htm

This test has no effect on our actual marks. It's supposed to be some assessment or something, and if you do bad.. well, I guess something bad will happen. 😛

In that case, there is but one option for you.

SWITCH TO LIFE SCIENCES!!! 😀
 
wow.......I think those questions are kind of tough...............I took calc I my first year in college(derivatives), calc II my second year(integerals), physics my 2nd year in college. needless to say, if they made me take that test the first week of frosh week, I would fail miserably..
 
warning: i'm doing this on little sleep, so take my answers with a grain of salt =P

1.1) {[(x^2 + x)^(1/4) * (2x + a)] / [1 - x(x + a)]^2} + {(2x + 1) / [(x^2 + x)^(3/4) * (1 - x(x + a))]}

2.2) X is a 2 by 1 array (just like B), and top element is 8/21, bottom element is -18/21

5.1) 4 * 10^-7 grams / liter

6.1) see dighn's answer below
 
the physics ones are pretty easy:
3-1 you need the acceleration which can be found from the deflection

a = g*tan(a) where a is the angle between the string and a vertical line, g of course is 9.8

since acceleration is constant, t is simple deltaV/a

3-2
two forces try to stop the car: Friction and Fbrake
Fstop = Ff + Fbrake
Fbrake = Fstop-Ff
Fstop = m*a, mass is car,, a is acceleration of car which is ccalculated in 3-1
Ff = Fnormal * coef = mg*0.1


to derive a = g*tan(a), use force body diagrams
 
Question 6-1 isnt really computer science, but anyway would it change? It seems to me that just adding an extra means of representing the program would have no influence as each switch is only in one state at any time.

well, it would. one bit of data can represent 2 states at any given time, which means 4e9 bits can represent 8e9 states at any given time. a trit can represent 3 states, so 8e9 states can be represented in (8/3)e9 trits.

actually I believe it would be 2^(4e9) bits for binary eg 1 bit 2 states, 2 bits 4 states, 3 bits 8 states so on

so the minimal number of bits would be 4e9*log(2)/log(3), if a decimal rounded up to the next whole number..

doh! omg, i cant believe i made such a stupid mistake =/ i'm a senior electrical engineer too =/ heh... good thing you caught it :beer:

I had calc like 2 years ago and I remember seeing these questions but I can't for the life of me do them if my life depended on them.

 
wtf you are supposed to have leanred linear algebra in highschool?!

2-1 infinite solutions (just substitute, pretty easy that way)
2-3 wtf?! (maybe graph it?)

Degree in ChemE ... no clue either. I may have known how to do these once ... about 5000 beers ago ...
 
POTENTIAL FROSH WEEK SPOILERS INSIDE

Hmmm... I don't know, but I think this might be a set up. I'm an engineer at Queen's, and they pulled something that sounds suspiciously like this does, on us during our frosh week.

We were told that we all had to write an exam which would determine our placement in the first-year class. (It was also noted that people who failed would be placed in remedial classes until they caught up; understandably this caused quite a stir.) When the test was given to us, I became extremely worried. There some VERY difficult questions on physics, calc, geology, and a few other things -- even for me (I was later ranked 9th out of 700 in the first year class, and I was 16 when I started first year). I started writing, and struggled with the first few questions.

But then the fun started. First, there were some noises, like beepers and small radios. The proctors "reminded" everyone that no electronics were allowed. Then, someone's cell phone started ringing. Whoever it belonged to answered it, and started talking to what sounded like his GF. So a proctor goes up to him and says, "Sir, I'm going to have to ask you to turn that off."

He says, "No way, man, I haven't talked to my GF for like, a whole week! Just give me a few minutes!"

This banter continued, back and forth, for a few mintues, until he was practically shouting. So then a few more proctors show up, and they grab the quy by the collar and bounce him out of the lecture hall. We could hear him yelling obscenities as he walked away.

So things settled down for a few more minutes. Then, we started to hear whispering in the crowd. Apparantly, the proctors heard it too. One of them yelled, "Hey, you! What do you think you're doing? You're not allowed to talk with your neighbour!"

The apparant offender stammered in response, "But I...." But it was too late. One of the proctors went up to him and tore his paper to shreds. As I recall the guy started crying and ran off.

Anyway, we settled down for a few more minutes. I think some people were starting to catch on, because I heard chuckling behind me (I was sitting almost right up front), but I was still oblivious.

When a proctor pulled a water gun from below the lecturn and started spraying everyone down, I finally figured that there wasn't much point finding the angle that the gutter had to be to maximize the amount of water held. Anyway, they really had me going.

Maybe I shouldn't even be telling you this, because it might ruin what is otherwise a good suprise.

(Also, if you're still thinking that the test is real, it's also worth noting that this "UTICS" website is part of the skule.ca domain and not the utoronto.ca domain.)

HTH, and have fun during frosh week.
