Dear Chemaxon developers and users,
I am happy to announce the availability of an online "test book" for organic chemistry prepared at the Institute of Chemical Technology in Prague, Czech Republic - http://ich.vscht.cz/projects/och/. It uses a custom made backend for data storage, but relies on the Marvin Sketch applet for user interaction. It is mainly focused on students of the ICT, but should be useful for any student of organic chemistry.
I would like to use this opportunity to thank Chemaxon for making their tools available for free for such projects.
With best regards
