    Write a function to determine if a student's cumulative risk score indicates they are at critical risk for dropping out and require immediate intervention. A student is considered at critical risk when their risk score follows the woodball number pattern, where the sum of all proper divisors of the risk score (excluding the score itself) equals the risk score.
