Change scene after reaching certain score.,Change scene upon reaching certain score

Hi I have a scoring system divided in two scripts, I wanted the scene to change when the player reaches a score of 3… Is it possible to add that feature without changing any of the scripts I’ve made?

This are the scripts.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class ScoringSystem : MonoBehaviour
{

public GameObject scoreText;
public static int theScore;

void Update()
{
    scoreText.GetComponent<Text>().text = "Objects Collected: " + theScore;

}

}

and

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CollectStar : MonoBehaviour
{

void OnTriggerEnter(Collider other)
{
    ScoringSystem.theScore += 1;
    Destroy(gameObject);

}

}
,Hi! I wanted to change to the next scene when the player reaches a score of 3, I have no idea of how to do this but I have a fully functional score system which divides in two scripts.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class ScoringSystem : MonoBehaviour
{

public GameObject scoreText;
public static int theScore;

void Update()
{
    scoreText.GetComponent<Text>().text = "Objects Collected: " + theScore;

}

}

and

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CollectStar : MonoBehaviour
{

void OnTriggerEnter(Collider other)
{
    ScoringSystem.theScore += 1;
    Destroy(gameObject);

}

}

Now, can I make that changing scene upon score = 3 without the need to change this two scripts?

Yes create a script with a reference to the score manager, and change the scene when the score is above or equal to 3:

using UnityEngine
using UnityEngine.SceneManagment
public class SceneManager : MonoBehaviour 
{
     public ScoringSystem scoreManager;
     public Scene scene;
     void Update()
     {
         if(scoreManager.theScore== 3)
         {
             SceneManagment.LoadScene(scene);
         }
     }
}
