Type 2 Conditional

Used for a non-fulfillable or difficult condition with a hypothesized consequence for the present or future; it uses the $simple\,past$ in the if-clause and the $conditional$ in the main clause.

Type 3 Conditional

Used for a no longer fulfillable condition with a hypothesized consequence for the past; it uses the $past\,perfect\,simple$ in the if-clause and the $conditional\,perfect$ in the main clause.

Mixed Conditional: Simple Past + Conditional Perfect
