Cpd dimers: Although your answers are correct, your discussion could use a little more work. It’s a tad brief, try to flesh your answers out, even use more diagrams or jmols to describe what you mean.

Taxol: All in all, you have the right ideas but it’s a little sketchy. Are there any other conformations the cyclohexane ring can take? How does this affect the energy of the molecule? What does the breakdown of energies of both isomers tell you about each conformation? Although it’s good to keep things concise try expanding on your answers with a fuller and more thorough analysis.

Carbene: Nice use of jmols. Again, though, your answer is lacking analysis. It’s not enough to simply state what is going on. Why is one alkene more electron rich than the other?

Glycosidation: Calculations but no analysis. If you don’t analyse your results then you’re missing out on a whole bucket full of (pretty easy) marks.

Mini-project: A pity you didn’t chose your own project. Nice to see you trying N and H NMR. Good use of jmols for the IR section. You state that NMR spectra are enough to differentiate between the molecules, if you make a statement like this you really need to back it up with evidence. It is not enough to simply paste spectra and tables, you must guide the reader through your analysis and thought process. For instance, compare the differences between your calculated spectra and that of the literature. Where are the differences? Why are there differences? Is the calculation accurate enough? Think of the best way to display this data to the reader (hint: graphs are useful, endless tables of numbers are mind-numbing)

Overall: Your answers were correct overall but largely lacking in analysis. Would also have been nice to see some introductions. Has the feeling of being slightly rushed.
