. . .the last subject for a lot of people, and argubly the best. . .if the 30% A rate is anything to go by. . .

Anyone got any tips, ect., past exam questions they suspect will come up?. . .I'll tip the partial fractions 1990 Hl Q10 (a) as the model for a hard question. . .came up in a Maths pre, and would be a nice trick to throw into the test. . .

Kedo93 · 17-06-2011 10:54am

My teach keeps suggesting that a bouncing question in projectiles might come up this year. Hasn't been up since 2001 I think. Also it's possible that we might get a question with two bodies moving towards eachother in linear motion, can't remember when that last came up but it's been a while

electrictrad · 17-06-2011 1:16pm

Anyone reckon theres a chance of topic crossovers, like 2002 Q4, where they put SHM in the connected question. . .

epicwinning · 17-06-2011 2:25pm

I read the 2007 Chief Examiner's Report and that heavily implied that people weren't learning Q6, Q8 and Q9 so there may be a bit of that. On the other hand, they might make those 3 easier to reward those who attempt it.

Phareon · 17-06-2011 2:59pm

Applied Maths is my last exam (obviously!), and I'm honestly not gonna study for it until after Chemistry! I probably should, since it's my worst subject (failed the Christmas and the Pre), but, for me, Chemistry's much more important!!
Our Pre was shocking though, our teacher couldn't even get some of the answers!
Out of the 6 in our class, the highest was like 46% (but she's, arguably, a robot though), next was me with 39% (Gutted btw

Almost passed.. ), then the rest were low 30's, high 20's!
I was thinking of doing Pass, but I'm probably not gonna count it anyway, so I'll stick with HL!
Here's hoping it all comes together before Friday!! The aforementioned 'high grade rate' is reassuring!!

8 and 9 are arguably the easiest questions on the paper, after 10

Anyone have any quick tips on deciding where to take your moments about on Q7? Always seem to pick the wrong place, and end up with reams of useless equations. I usually try to either eliminate unnecessary variables (reactions etc) or just eliminate as many as possible, but I always seem to fudge it up.

larkin1993 · 17-06-2011 6:58pm

Normally I find its best to take the point with the most forces going through it

krisityfer · 17-06-2011 9:03pm

Yeah, that's probably the best option, just I always seem to differ from the marking scheme's choice.

LilMissCiara · 17-06-2011 9:06pm

:O The poll results all have 11 in them...!

luciemc · 17-06-2011 10:06pm

haven't looked at it yet..? hoping two days will be enough? still have physics, accounting, Spanish and chemistry to get through so it's the least of my worries:( screwed for accounting.

and yet, I can't get off facebook or boards? <_<

Haven't looked at it either!
But, seriously you've got 5 subjects left, and some people have been done since Tuesday! That must suck :O
I've only got 3 left, 3 of my worst, but the ones I really need to do well in :P

Thats because the poll was annulled. . .a moderator must have deemed it inappropriate, or something like that. . .

Mr. Maths · 18-06-2011 6:59pm

Advice from the chief examiner's mouth people, the best option is not to pick what questions you're gonna do until you're actually in the exam. That way you can avoid any scaldy questions if they come up and just do the easiest ones

It does take more prep though is the only thing.

Inappropriate ... depending on how you understand the word, that's probably a bit strong.

Likely just to raise stress levels when people would be far better off just getting a bit of study done, yes.

I'm not a great fan of the constant preoccupation with numbers and comparing them ... I wrote " " pages, I reckon I got an " " in that, I think I have clocked up " " points.

It's understandable of course, but a lot of the time, it just puts yourself (or others) under additional stress ... especially during the actual exams.

Also not allowed do this any more! Its widley excepted now by the SEC that everyone studies Qs 1-5 so there can be slight mixes with respect to these, eg es in projectiles ect. And teachers chose after that eg we do 7,9,10 not the others! There was uproar in 2002 and they wont be doing it again!:)

They more than likely will mess with at least 1, if not more, of the base 6 questions that most people cover (1-5, 10). They may mix 1 and 5, they might mix 3 and 5, you cant say what they'll do before the exam =]

I never said they wouldnt mess with any just that they cant mess with Qs 1-5 by putting in parts of Qs 6 and up. I said that yes they can mess with 5 and 3 but they won't repeat the 2002 mess up.

Maybe_Memories · 19-06-2011 6:14pm

Back in 90-something they threw SHM in with Hydrostatics
And in the mock paper I had last year

Stretch101 · 20-06-2011 2:27pm

Watch question 2 and 5 as they are the questions that they can twist to make it deliberately difficult.

deiseguuy93 · 20-06-2011 3:00pm

Question 2 is definitely the easiest one in the paper for me! and as long as they ask your basic derivations without complications i should hopefully be fine!

Or if there are strange things, like i remember in a question a plank was sticking out of a wall, you wana try cancel out that reaction cos u don't know squat other than it exists.

If two are leaning against each other, and your taking it as seperate planks, you have your 'x' and 'y' reactions at the top/where they meet (whatever you call them), you generally want to take moments about there as those are 'known unknowns', as our distinguished political class would say.

do your force diagrams first and then pick a point where you can have easy horizontal distances! that or go for the part that seems to have the most going on. Or go for the far left/right

japester · 22-06-2011 12:15am

Very good advice for applied maths exam is to make sure you write down the equations of motion/force in the various questions correctly e.g. in collisions, get the PCM and NEL right (in the log book also), in the kinematics get the equations of motion right (in the log book too) as they are worth a good chunk of the marks - the manipulation of equations to get the final results, while it may take a lot of time & effort, is generally not worth a lot of the marks overall and people invariable get bogged down, even though they may have just made a small arithmetical slip or blunder in a formula. Take some time to pick out your best question and then attempt this first. Definitely move on your next best question after 25 minutes have elapsed, irrespective of how far you have got with it. The 2.5 hours goes very fast and 6 questions is a fair amount of work to do. Q10 (a) may well be the best question to start with if you can integrate, as it is varies little from year to year, also Q10(b) usually is very predictable involving variable forces, acceleration, velocity, displacement etc. I have a feeling that a study of hydrostatics could pay dividends if people took the time to look at it, as there is not a massive amount of material to cover. Hope this info helps someone out there.:)

But yes, Friday Night...... Cannot wait!

Most of the marks go for setting up the questions though, so once you get the equations written out you should be close enough to a b2

and then some attempt marks from trying to work them out youll be grand!
I'm so tempted to go out thursday night too because all my friends are finished then

Buuuuuut past experiences tell me maths isn't too easy hungover xD

Haha, bad idea me thinks..! Especially when it's a morning exam..! The old 'Ah sure I'll only go out for one, I'll be home by 12'' never works! :P

It sucks, all my friends have finished today, or earlier!

Perfect solution methinks :L Hmmm I'm lucky though, I dont need applied maths for points!

I dropped History in school (did App Maths out side of school) because it was such a tediously boring subject (and the teacher was dreadful!). I don't regret dropping History, I regret not doing something else at the start!

I do pass Irish, so Applied Maths is one of my 6 honours..! I never covered collisions in the class I went to (I stopped going after Easter) so I get stuck in the b parts..!

Haha.. Spoz I get stuck in the whole paper really..! :L

I may as well have dropped history and done pass Irish for all the good they are to me points-wise

Made a total mess of both the papers! Expecting d's in each

but I'm grand with the other 5 i've done so far so all I want is to pass Applied maths now

This dude, for the sections he has actually covered, is a wonder. I was barely able to do a nice q10a before, and now i breeze through most q10s. He's a massive help.

For proofs/theorems - our teacher just told us learn what was in the book and write that out, DID NOT teach them to us, and the book was more of an explaination so that we could understand what was going on, not a concise proof.

If anyone has these down, or a link where i could find them, that'd be fantastic, cos i really don't know if what i write for them is correct.

aranciata · 22-06-2011 8:50pm

Are people predicting this paper to be easy or hard? Last years paper was a cinch in comparison to other years.. let's hope it's just getting easier cause I am hopeless at questions from earlier years! If it's anything like the first maths paper this year, I am going to die. I won't be able to cope with anything anymore and my heart will just stop beating.

Geog ariphic · 22-06-2011 8:53pm

only the standard "read all before hand and pick those you've seen before". Read all of them though as there is usually a twist in the fine print of the question, or at the very end.

On the other hand, do questions 7 and 10. Apparently very few do 7 so there's never much of a challenge put into it (says my teacher.... seems reliable enough from past papers), and as another poster said above, 10 is often mostly doable. (That said, setting up the equations to part b can be a giant pain sometimes...).

Do 2 and/or 3 if you are good at them. Personally i am good at 2 but not 3, so i'll defo be doing two unless its impossibly different from previous years.

1...really depends. Sometimes can be lovely, sometimes like maths they reckon everyone will start with it so they throw in something to catch most people out. Read it thoroughly. I'll probably have to rely on this regardles..:/
