I'm going to FAIL my economics exam so bad

Shove tutor2u in google, that should help you out!
It's for A level, but most of the stuff still applies.

I have done, its too complicated though and still doesn't explain those diagrams to me!

1. You have a negative attitude, i.e. "I'm going to fail...". By saying that, you will. Be bloody optimistics.

2. "I can't really understand the diagrams at all...". Get a lecturer, someone on your course etc to help you out. Not on here. Because materials differs between every uni, and also, it would be so much easier if you get someone to help you from your uni.

3. "exams are coming up in a week... they're [the diagrams] are so complicated". What have you been doing for the past weeks? In fact the past year? Please, don't give me "getting drunk, procrastinating" etc. If this is the answer or similar, you now have to face the consquences. Happy cramming stuff you don't understand.

On a serious note:

* Sort your attitude
* Have a better work ethic
* Get someone on your course to help you
* Stop procrastinating
* Get down to some serious revision
* Let this be a lesson to learn

but you're at uni.......... surely you should understand basic A level economics What uni you at? youtube pajholden for help

PPFs, pfft there piss, I'm only doing A Level as well

Oh yeah OP. What bloody diagrams? How is ANYONE supposed to answer your question if we don't even know what diagrams you're talking about?

If you're serious about passing, answer these questions which would make life so much easier for you, and for us:

What uni do you go to?
What bloody diagrams do you mean?
Describe in detail the parts you don't understand. (For the sake of your dignity, please don't say "all of it")
Ever tried going to the library and actually working? You can't understand something if you don't work. If you get stuck, ask help from your coursemates.

my course isn't economics, its just a module we have to do.
and yes i do admit i haven't worked hard enough throughout the year... but all my friends in second year didn't do any studying and all got 2.1s (i know that makes me sound incredibly naive).

and i've already seen my economics lecturer twice, i think he might get a bit pissed off with me if i have to ask him questions again!

i swear i've already said lol...

but:

tariff diagram
subsidy diagram
quota diagram

i just don't understand all the different triangles and squares... surely someone here does economics?

Be specific next time.

"I haven't worked hard enough throughout the year".

Good news: You admit to it, and not covering up like a stupid little plonker.

Bad news: WTF? Exactly WHY didn't you? Why? Answer me. Sort your work ethic and limit procrastination.

"All my friends in second year didn't do any studying and all got 2:1s"

That doesn't mean you bloody should. You got get a first if you put your mind to it. Just because someone did "no studying" and got a 2:1 means that you would too. Maybe they worked hard throughout the year? Maybe they actually understood the material and the "diagrams"? Maybe they did study (which is very likely ), but didn't want you to know? Why? What right should you have in their study plans?

well i dont know if you're at uni... but the general feeling of first years i know (and i know a lot of people) is screw good grades, 40%.
(that is all you need to pass the first year)

well as i'm so academic is so unhelpful (and note there are very few diagrans for these concepts, so most a level econ students would be able to explain)
this is the diagram i'm explaining from
http://www.worldgameofeconomics.com/EffectsofTradeBarriersopt.jpg

ok you see the domestic supply curve and the demand cuve- thats your basics, and where they meet that's price
the lower horizontal line is global supply- its perfectly elastic because it's perfectly competitive, (i'm hope you understand that term-= it means that in effect, the goods sold are exactly the same, there's perfect knowlegde of the market so everyone produces at that price)

ok so basically, domestic firms are producing at Q1 and imports are coming in from Q1 to Q4, basically means unemployment for some domestic firms, they are struggling with globally lower prices- cheap labour from China etc. so they moan and the government impose a tariff which is a tax on imports, shifting supply to the upper horizontal line, meaning that domestic firms supply till Q2 and imports Q2 to Q4
the letters on the diagram A+B+C+D= loss of consumer surplus due to increased price due to tax, B+D are deadweight welfare loss (ignore if you don't understand), A is extra revenue for domestic firms and C is tax for government
that diagram is standard econ a level diag and then define what the letters mean

Unhelpful? Excuse me?

I know I'm not in a position to be able to directly answer the OP's question, but I can give some advice which would indirectly help the OP. E.g. the OP has a negative attitude towards education, and I was just giving some advice on how to sort it out.
Gosh, if you don't like my advice, take it or leave it. Because I would find that some people would find that my advice is actually quite helpful in a different way.
