[5.01/5.09] ChemWorld

ChemWorld at Thinkquest.org is a pretty well-designed site for those aiming at post-secondary courses like AP Chemistry and IBDP HL Chem. I would like to draw attention to the friendly formatting and reasonably well-designed pages. The layout is OK, although sometimes the text is too close for comfort. Enjoy. And revise for the test, which I shall endeavour to hold on the day latest in the week.
