Memorize C-H torsional strain values?

Anyone know if we will be expected to calculate the K from the difference in gibbs free energy of two conformations? And if so, do we have to memorize that a C-H eclipsed pair adds around 4KJ of energy?

I don't think you have to memorize the exact values but it would be helpful to know which conformations have higher energy values than others. You can usually figure this out by looking at which atoms are under strain (e.g. a C atom and H atom, two C atoms or 2 H atoms).

We won't be asked to calculate any of these quantities for conformations then? I believe it's covered in the o-chem textbook but I wasn't sure if it would seem on the final.
