error CS1525: Unexpected symbol `&&' How do I correct this error

I am trying to access an script. I have an error on line (22,30) and 17. Here is my script.

using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI;

public class Game : MonoBehaviour { private scoreManager scoreManagerScript; private myClock MyClockScript;

  void Awake () 
  {
      scoreManager = GetComponent<ScoreManagerScript>();
      myClock = GetComponent<MyClockScript>();
    }
 
  void Update () 
  {
     if ((myClock != NULL) && (scoreManager != NULL))
     {
         
         
     }
       if ((m_leftTime >= &&  < scoreManager.score))
      {
          SceneManager.LoadScene("time");
      }
  
   

}
