I want to prepare for my National Olympiad but I ran out of sources. I solved old IChO problems, US National Olympiad problems and I also went through all ''problems of the week'', so don't post them. Ukranian and Poland tests are too different from my nation's so I don't need them either. I would like organic chemistry problems, too. If someone knows a good link to some tough problems I can practice on, please post it here, I would be very very thankful.

What's "your nation"?

You can look for other countries' selection tests (I'm sure you have already), but here are some more:

Britain: http://www.rsc.org/Education/events-and-competitions/Olympiad/olympiad-questions-answers.asp
Australia: http://www.chemteam.info/AChO/AChO-Menu.html

The UK Olympiad reminds me to new IChOs (because they are long, they have a) b) c) d) etc. which aren't related so much) and it is different from my nation's problems. The Australian is mainly based on quick questions which don't work either. I was looking for problems that are similar to the ''problem of the week'' here and old IChOs. These aren't too long problems.

I am sorry, I can't share private info  . I am looking for free problems, I can't buy books.

Found just the Belarusian. It is really good. It has a) b) c) d) in problems, but they are only guidelines to help determine the final result like in the US national Olympiads.
Anyway, thanks for the links you two gave me, but I am still hungry for more  . If someone finds something interesting, please post it.

Here you will find practice organic problem sets, tests, and notes, just browse around:

Organic I:

Wow, that is good. Thanks very much  .

Woah that's a lot of stuff! When is your Olympiad? I'm also trying to prepare for the national Olympiad which will happen in a roughly a year's time... Obviously I'm not as motivated...

Have you tried the IChO Preparatory problems? There are quite a lot.
you can try here:
http://chemistryolympiad.weebly.com/preparatory-problems.html

For organic my seniors actually recommend doing all the problems in the Clayden organic chemistry book. but if book is not an option then...

Hehe good luck!

[Rutherford]

It is in half a year from now. I solved the old IChO problems, but the new don't fit to the type of problems I am looking for. I will search for Clayden in .pdf format on the net. I wish you luck, too.

[Sophia7X]

Raderford, did you do the 2012 iChO predatory problems? I am having a bit of trouble on them.

[Rutherford]

No, I was solving only the older IChO problems, mainly before the 30th, but I also solved few after it. It's because of the ''Topics of advanced difficulty''. I don't have enough time to learn them for every Olympiad and I don't have to, because we don't have those in my country's Nat.Ol.
If you don't have the answers to the 2012 IChO preparatory problems, I can send you. Do you have them?

[Sophia7X]

Yeah, I have the answers; I just wish they would elaborate more in the solutions.

I've noticed that some years are much better at explaining than other years.

 I know there might be several topics with the same subject. But starting a new topics works better!

So I'm currently studying for the olympiad . There are three levels here in our country in which we should take part. The 1st and 2nd ones contain nothing but general chemistry. The 3rd level , which is of course the toughest one , requires us to go over organic , physical , analytical and inorganic chemistry subjects. Here are the books I've already read :

Organic : Mc Murry , Solomons , Vollhardt and Morrison"s
Analytical : Skoog , Harris and another one called : Problem solving in anlaytical chemistry

I was wondering whether there are any other useful sources I still need to read. What books do you use to prepare yourself for the national exam in your country? (I'm mainly asking for organic and analytical ones)

Thanks in advance
& sorry for my bad English!

[Sophia7X]

I use Wade and Klein organic chemistry. I also have Atkins' physical chemistry.

If you are taking your country's National Olympiad then surely your final aim must be the IChO this year? In which case you will have to adapt to the modern style of IChO questions!

I find that a lot of what the past IChOs present as "topics of advanced difficulty" are actually not beyond the high-school level. I have usually covered all the physical or organic material without revising. And often the same topics crop up, e.g. kinetics, Gibbs' free energy, etc. So if you just mug up on these topics from a few semi-undergraduate sources (readily available online) you can still practice IChO questions from "topics of advanced difficulty".

[Rutherford]

I saw the modern type of problems. They contain a lot of questions. Some are really dumb, but some are very hard. I actually learned some topics that I didn't need to for the National Olympiad, and I will probably check the advanced topics and preparatory problems of this years IChO, but where are they?
