About This Set
These questions are harder, and many of them join two ideas, such as the 9-test and the 11-test together for a missing pair of digits, or an LCM with a remainder that must also be divisible by 11. Items marked [Tier 2] use methods that only Tier 2 tests, so you can leave them for later if you are preparing for Tier 1 alone. Allow about 30 minutes. With 18 or more right, this chapter is ready for the PYQ sets.
