On my last lecture at the Telerik Academy on January 5th, 2012, the students were presented with various numeral systems (the usual base 10, the binary base 2 and the hexadecimal base 16).In my humble opinion, this presentation came a bit too late, since the students have already been handling variables of all primitive types (after the "Primitive data types and variables" lecture) and manipulating them quite on a low binary level (after the "Operators and Expressions" lecture).
If anything, this lecture, which includes explanations of the basic count systems and memory representation of primitive types, should have been presented before learning about the various types themselves.
