In this lecture we survey all the things we skipped/ran out of time to cover during the course itself. These include:

• The Hurewicz Theorem,
• The Blakers-Massey Theorem,
• The Whitehead Theorem,
• Approximating spaces by cell complexes,
• The general existence-uniqueness result for Eilenberg-Steenrod homology theories (we proved the "baby" version of this theorem in Lecture 21-22.)

Everything in this lecture is (of course!) non-examinable.
