Things that can be ignored:

Quantum Numbers
The Nernst equation (n=It/F)
Intermolecular Forces (boiling points, ionic/covalent bonds, etc.)
E=hc/lambda=hv

Things that are likely but only 1-2 points:
Radial probability density diagrams/orbital diagrams

Questions that are good to understand: Winter 2013 Q13 (which species is the strongest oxidizing agent – last exam), Winter 2013 Q23 – great run through of a titration.
