Cp: Energies and structures are fine. For the explanation of the endo product - you mention an interesting bis-pericyclic TS concept, but don't give a reference to it! And then you give a reference to a (poor) Wikipedia page! It's MUCH better to explain in your own words and refer to original papers, reviews or books. Avoid references to Wikipedia (there is lots of junk on there). I like your explanation of bending energy in 3.

NAD: Looks OK. The "Possible Improvements" bit is empty!

Taxol: Your structure 9 is the wrong alkene geometrical isomer. 10 is OK. Nice idea to model the hydrogenated compounds. Why, in terms of structural features, are they less stable?

CCl2: Orbitals, frequencies for 11/11H look OK. You've correctly accounted for the C-Cl frequencies, but what about a comment on the difference between the two alkenes in 11? Your ChemDraw of 11a-c is missing so I don't know what they are, but good to see you tried this.

Mini-project: Very good choice (!), but not much discussion given. Would have been good to explain what's going on in the Scheme you've drawn. You also needed more discussion about the agreement between calculated and experimental 13C shifts. At first glance, the first isomer looks to agree well; the other less so. Why is this? What particular carbons are in error? As we discussed, NOE(sy) would be a key technique to tell these isomers apart, especially if 3J-values were not useful. But I'd like to see more discussion on how it would be used, not just a couple of sentences on what it is.

Overall - some good stuff here, but I get the impression you ran out of time! That's a shame, because some more discussion would have helped your project in particular.
