any thoughts on what should we cram in the days coming near to DCG? ive wednesday off and will have a little bit of time to spend goin over questions. I know short questions cover a lot of topics, but for the long questions what ye think?

intersecting solids is an easy question when u know how to do

eats up alot of time tho. i'm avoiding that unless i get caught with other questions. skew lines or solids in contact are much eaiser to do in the 20min you have per qu

20 minutes for a long question? Isn't it 40 minutes? But yeah, I do agree that Interpenetration takes longer than the time you have although it is a pretty easy question

actually yeah, what is the timing for each section/question..!?

From a suggested time scheme our teacher gave us i have just dug out.

short qu - 12min each
long qu - 35min each

2.00 - 2.35 your best long qu
2.35 - 3.10 second best long qu
3.10 - 3.45 3 short qus
3.45 - 4.20 3rd long qu
4.20 - 4.55 4th long qu
4.55 - 5.00 finish off/correct

cool, maybe intersecting solids could come up again? that paper last year was easy when ya look back on it... like the oblique plane question and intersecting planes..class like! fingers crossed this year wont be too bad!

Eire-Dearg

Hopefully intersecting solids comes up... I found it absolutely impossible at first but its a million times easier if you keep labelling your points and what lines they hit.

I'm hoping for a nice interpenatration,assemblies,dihedral angle and dynamic mechanisms question.I have like 3 days to just do dcg so I shoulg be grand.Go over like 6 questions a day and then one of each just before the exam on friday.Only thing I really see screwing me is section A!!:(

Ok I'm seriously screwed for this... And I'm doing higher level T_T

What should I cram within these days?

Interpenetration is okay. My teacher said around half the marks are given for drawing the plan and elevation, finding the inter penetrating plane and starting the auxiliary.

Thank you! What long questions are predicted to come up? Also what should I do with the short questions?

Whats the story with margins?

Sorry if this has been asked already but theres so many dcg threads to trawl through

Do we need to draw in the margins for the exams? Are they worth marks?

Ya those are my bible Im just confused though beacause the sample answers have borders but nothings mentioned about them in the marks.
And what way do we label each sheet?

its impossible to learn it from a book but if your teacher is decent its a great subject! Once ya understand why your doin what your doin ya can sort any question yourself...like my teacher spends half the class explainin why ya draw an auxiliary or why ya sswing something around to 3 o clock....75% of the class are goin for A's, myself included:D

Everyone doing DCG, envies you *sigh* :mad:

johnmcdnl

it's such a prick of a subject.. worst mistake ever picking it.. I should have done russian or japense or anything really other than it.. i loved it til the junior cert but then I decided to pick it because of the project -- now all I can do is the lines in space and stab a shot and the circles in contact question or whatever it's called.. i'm ok at the maps too but other than that... my teacher told us not to get the books because there rubbish and we wouldn't be using them anyway so...

worst mistake ever pickin this subject.. i'm seriously worrying about it like because I can't even look at the short questions or the interpenetrating questions...

I actaully love it and the book I have is actually unreal!!!I taught myself interpenetration and dynamic mechanisms through it.It's the one that has 2 parts,one red and the 2nd blue.Great book!!!

Conor108

Im hoping for a near identical paper to last year. Or at least very similar. I'm actually OK at section but C but A & B god...lets not.

Countdown to 906 BETTER do DCG on thursday night...

I thought that was the only book.. it's ok i find the questions dont really match the manner in which they'll be asked in the exam...

Currently going through those slideshow things the teachers have, anyone want them? specify an area if you do its a big file..

What are they like? Is there one on interpenetration?

Did you get those off T4??

Conor108

Hate the ones off T4. The writing goes off the slide usually on top of other writing. They pile clip art on top of each other. Its so bad.:(

UpTheSlashers

The t4 ones are available to anyone on th internet aren't they?

wonderfulname

Yea we've established is the t4 ones oh well, and some are better than others they're all done by different people you see..

Mescaline

I dont even no where to start, my teacher cant explain so i gave up on going to the class.. i just have to pass the subject as i do 7. but i just dont want a big F on my LC results.. and i think id have more of a chance passing a subject i never even did,

But i did the project at honors level ( Worth 40% ? ), my project was perfect, i didnt go to any classes for about two weeks working hard on it. so im hoping for high marks in that. but theres not a chance i can complete or even understand a question on the paper. and its to late to cram as i dont understand alot of it even.

So what im wondering is can i do the paper at ordinary level, Even though my project was done at higher level ? and if so is the project worth the same marks.

-OR-

Whats the minimum i would need to do in the paper if my project was high.

Alot there sorry,
Thanks.

UpTheSlashers

I'd concentrate on section C, the same 5 topics are in every paper I've seen so you just need to study 2 of those for 90 marks (out of 400, nearly 25%)?

Please correct me if I'm wrong anybody

Qwerty?

Your project will be marked on the HL marking Scheme regardless of the paper you sit, and then added to your OL DCG written exam mark if you change to OL. Surely if you have done such a good project (35%+) a little practice will get you the few percent you need in the exam?

22.5% almost there! THANK YOU for pointing that out by the way, Had no idea section C was that! Im actually pretty decent at section C and my project was decent! Section A will be touch-and-go, B will be mostly completed by 'drawing the given plan and elevation':D

Jesus I could well scrape a C in this long thought to be impossible! You have given me hope!

Oh okay thanks, so say 35% HL After corrected Would just convert to 35% OL.
Hm Yeah i would be better off trying the higher and pass, just fear that some ridiculas projects might push the standard very high. and i then fail.. I Dont understand the wording in the short questions or how to do any of it.. never taught.. and for the Core I know a bit about planes (dihedral angle,intersect,plan elevation) And for applied graphics i could attempt at structural forms and assemblies. Never learned them but they look fairly easy. Could the short questions be anything ?

The short questions can be on anything from Section B (the Core).
I'd suggest that you Practice a few Trimetric Questions and maybe Perspective, likely to be in either Section A or B

would they have a perspective question in section B? i'd love that, they're simple! :cool:

I'm REALLY hoping that they ask for perspective, axenometric and solids in contact in section B - they were in section A for last year's exam and they're all usually incredibly easy. If oblique planes come up, however, I may cry.

I'm a graphic designer (did my LC in 2000) - this course sounds very interesting. All they had was regular art in my school which didn't suit me but glad to see such a topic being added to the LC.

Learn something new every day

johnmcdnl

it's still the same course hidden behind a new name and by giving 40% to a project

Screwedforlc

does any one know where i can get some questions to practice ? T4 not a great help and its too late to get to edco papers

Doubt that's gonna happen.Since it's only a new course they probably won't vary the paper by much so expect something similar to last years

Yes but that 40% is a pretty big deal don't you think? Makes the course far more in touch with the real world.

Just a quick question on geologic geometry:

Point A is at 60 metres
A to B has a gradient of 1 in 20 rising
Embankments are 1 in 1
I came along 100 metres and said this point is at 65 metres (Is this even right?)
What do I do next?

What is the difference in height between each contour line?

Ok.

So, where you have marked off 100 metres on the road, you draw an arc of 5mm on the edge of the road. You then draw a line from A to the edge of your arc. This is now your 60 metre line. Then you just continue on as usual, drawing parallel lines to this new line at intervals of 5mm.

How do you tell the measurements (size of the arc, I guess) for when it's cut and when it's fill? This is what I can never tell.

Also, what does 1 and 20 rising mean exactly?

Thanks!

The ones with the parabolas are conic sections

In the question you are kinda given them. Take last year for example

Using side slopes of 1 in 1 for the cuttings and 1 in 1.5 for the embankments,

1 in 1 means that you just use the difference between each contour line as the measurement (usually 5). 1 in 1.5 means you just multiply 5 by 1.5, which will give you 7.5mm as your measurement.

Also, what does 1 and 20 rising mean exactly?

Thanks!

This means that for every 20 metres the road advances, the height will go up 1 metre.

Hope that helps!

Parabolas could be an Oblique planes question but it comes up in other things aswell

The Radius of the arc is determined by how far you come out from your point A and the sideslopes i.e. If it's 1 in 20 rising and you come out 100, then you rise up by 5 (You come up in intervals of 5 because of the existing contours). If sideslopes for embankment was 1:2 then for every metre you come up, you have to go out 2, so If you measure 100m along the road then you are rising by 5 which means you have to come out by (2 x 5) 10 to find the radius of the arc/semi-circle. The Cone goes at the high point of the road for Embankment and at the Low point for cut

Eire-Dearg

So if its 1 and 20 rising you got 100mm from A to your next height?
