I am an A-level student going into university and I am looking for a source of organic synthesis problems and answers that is freely available on the internet. The difficulty level I am looking for is something like first year undergraduate level. Any links would be greatly appreciated.

$\begingroup$ I believe there is some site where you can practice synthesizing a compound (theoretically of course) by selecting reactants and starting materials. Very nice idea, but unfortunately I cannot find it anymore... anyone? $\endgroup$– JoriCommented Dec 11, 2014 at 19:10

Search for the latest IChO tests and preparatory problems. You can find quite a few interesting problems.
Here are some tests: http://www.iuventa.sk/files/documents/5_icho/past%20competition%20tasks/volume3-icho41-45.pdf
http://icho2013.chem.msu.ru/materials/Preparatory_problems_IChO_2013.pdf (problems 18-21)

Janice G. Smith's textbook "Organic Chemistry", while unfortunately expensive, has a good interactive workbook online which is useful even without the companion text.
You can find it here.

$\begingroup$ That website is not working for me. Does it work for anyone else? $\endgroup$– yolo123Commented Dec 11, 2014 at 22:38

$\begingroup$ @yolo123 Select the chapter, then open the corresponding multiple choice quiz. $\endgroup$ Commented Jan 7, 2015 at 21:29
I would recommend doing textbook problems e.g. those of David Klein and Clayden. In addition, it might be useful to refer to MIT open courseware's organic problems. I have included their links:
https://ocw.mit.edu/courses/chemistry/5-12-organic-chemistry-i-spring-2003/ https://ocw.mit.edu/courses/chemistry/5-12-organic-chemistry-i-spring-2005/
These problems might be old, but I still found them useful... As for which year to do, I don't think it matters too much
