The Identify Number of This Carbon or Ring Letter Quiz has been revamped. Now, you will see the correct numbering of each carbon and lettering of each ring displayed on the structure after you choose an answer. The correct and wrong answers will still be highlighted in green and red respectively. After the quiz completes you will see the entire numbering and lettering displayed on the structure for easier memorization.

The app has been revamped significantly. Now, you see the entire network of biosynthetic pathways and you choose each molecule by name or each name from each displayed molecule; instead of studying each individual pathways. If you choose the correct answer then the molecule name or molecule structure will be highlighted in green. If you choose wrongly then the wrong answer will display temporarily and then revert to the displayed name or structure 'question'. Some screens should be viewed in landscape mode and some should be viewed in portrait mode for best viewing. On smaller screen sizes all that you need to do is drag to see more of the View.
