When completed, college admissions officers should be able to use the Java program to determine whether to accept or reject a student, based on his or her test score and class rank. start input testScore, classRank if testScore >= 90 then if classRank >= 25 then output "Accept" else output "Reject" end if else if testScore >= 80 then if classRank >= 50 then output "Accept" else output "Reject " endif else if testScore >= 70 then if classRank >= 75 then output "Accept" else output "Reject" end if else out put "Reject" end if end if end if stop Instructions Study the pseudocode in picture above. Declare the variables testScoreString and classRankString.
