Key discussion points from the group session on Faraday's Law and Lenz's Law. The main takeaway was understanding how to determine the direction of induced current by opposing the change in magnetic flux. The right-hand grip rule is crucial.

An AI-generated summary comparing SN1 and SN2 reactions. SN1 is a two-step mechanism favored by tertiary carbocations, involving a planar intermediate. SN2 is a single-step, concerted reaction favored by primary substrates, resulting in an inversion of stereochemistry.

Remember to revise trigonometric identities and differentiation rules before the next past paper session. Specifically focus on the chain rule and product rule.
