Adding score in if statement within Update() happens continuously.

Hello,

I am making a game where a player navigates a maze and gets points after completing the maze. The old maze should leave the game and the new maze replace it and the score based on how long it took to navigate the maze appears. The problem is the score keeps adding and the new level never comes in. Here is the code in my Update() method in my GameController class.

 void Update () {
 
         GameObject currentLevel = GameObject.FindGameObjectWithTag ("clonelevel");
         if (currentLevel != null) {
             xPosLev = currentLevel.GetComponent<Rigidbody> ().transform.position.x;
             //Debug.Log ("xPosLev is " + xPosLev.ToString());
         }
 
         if (BallMover.GetTouching () == true) { //Player touches right answer
             enableScoreAdding = true;
             winPoints = 10;
             EndLevel ();
             mathProblem.text = "CORRECT!";
         }
 
         if (BallMover.GetTouchingWrong() == true) { //Player touches wrong answer
             winPoints = 0;
             mathProblem.text = "WRONG!";
             EndLevel ();
         }
 
     }

I tried to stop the score addition by creating a variable enableScoreAdding so that when the score gets added in a loop it then, after once, sets the variable to false. This has not worked. Here is the method where the score is added and called (in the EndLevel method).

 public int CalcScore()
     {
         Debug.Log ("Adding 10 to Score");
         if (winPoints > 0) { 
             scoreBonus = (int)((100 / Timer.GetTime ())) * (Timer.GetTime ());
         } else {
             scoreBonus = 0;
         }
         return winPoints + scoreBonus;
     }

This method makes the level fly out and it is destroyed when it contacts an offscreen gameobject.

 public void EndLevel()
     {
         //changingLevel = true;
         GameObject thisPlayer = GameObject.FindGameObjectWithTag ("Temp Player");
         Destroy (thisPlayer);
         GameObject thisLevel = GameObject.FindGameObjectWithTag ("clonelevel");
         if (enableScoreAdding == true) {
             score += CalcScore ();  //Increase score
         }
         enableScoreAdding = false;  //Stop score adding
         scoreDisp.text = score.ToString (); //Display score to screen
 
 
         if (thisLevel != null) {
             Rigidbody rb = thisLevel.GetComponent<Rigidbody> ();
 
             answer1.text = "";
             answer2.text = "";
             answer3.text = "";
             answer4.text = "";
 
             a1.enabled = false;
             a2.enabled = false;
             a3.enabled = false;
             a4.enabled = false;
 
             rb.isKinematic = false;
             rb.AddForce (transform.right * 100f);
         }
 
     }
