Notes

The lecture contents of TC-A in winter and summer terms differ. The winter term's subjects are more fundamental and basic.

If you are free (of scheduling issues) to choose I recommend attending the winter term's lecture. However, the summer term's lecture is self contained and may be attended independently. Both lectures are (offline) mostly black board type lectures. In the winter semester there is also a number of computer animated illustrations.

In any case you should have a theoretical interest and no reservations about math...

Many students before attended one term as TC-A and the other as S-module.
