LEVEL Intermediate

Sufficient and necessary conditions are some of the most common logical elements encountered in logical reasoning. Easily confused with each other and often unintuitive, they can make for some truly hard SA and NA questions! This class will cover the concepts and strategies that are essential for effectively navigating both question types.
Difficulty: 2-5 stars
