Hi tmmaluleke!

You got a typing error in your exclusive gateway. You wrote "student" instead of "studentId" ;-)

<sequenceFlow id="_5-_6" sourceRef="_5" targetRef="_6" name="Accept" tns:priority="1" >
      <conditionExpression xsi:type="tFormalExpression" language="http://www.java.com/java" >return student =true;</conditionExpression> 
    </sequenceFlow>
    <sequenceFlow id="_5-_7" sourceRef="_5" targetRef="_7" name="Reject" tns:priority="1" >
      <conditionExpression xsi:type="tFormalExpression" language="http://www.java.com/java" >return studentId=false;</conditionExpression>
    </sequenceFlow>
