Chain coach

Marks are lost when an answer jumps from the cause to the result. Learn to build the chain in four short steps, from spotting a jump in someone else’s chain to writing your own with no help.

  1. Spot the leap in a chain with a link missing.
  2. Order the links of a chain.
  3. Build one, a link at a time. Revvy asks about the weak spots.
  4. Do one on your own. It practises your analysis. It does not give marks.

Ask the tutor about Introductory Concepts

For example

Why does a tax on cigarettes not cut smoking by much?

Demand for cigarettes is price inelastic: they are addictive and have few close substitutes. So when the tax raises the price, the quantity bought falls by a smaller percentage than the price rises.
