Answer
See below.
Work Step by Step
The contrapositive of $p\rightarrow q$ is $\sim q\rightarrow p$.
The converse of $p\rightarrow q$ is $q \rightarrow p$.
The inverse of $p\rightarrow q$ is $\sim p\rightarrow q$.
Hence here the converse is: If no students fail the test, then the review session is successful. The inverse: If the review session is unsuccessful, then some students fail the test. The contrapositive: If some students fail the test, then the review session is unsuccessful.
