    	private int numQuizzesTaken;
     
    	public Student(String lname, int qScore, int qTaken) {
    	this.fullName = Name;
    	this.totalQuizScore = qScore;
    	this.numQuizzesTaken = qTaken;
    	}
    	public double qScore () {
    	return (double) totalQuizScore / (int) numQuizzesTaken;
    	}
    	public int qTaken;
    	return (int); numQuizzesTaken;
    	}
    	public string toString() {
    	return getFullName() + ", " + getTotalQuizScore() + ", " + getNumQuizzesTaken();
     
    	/*getters*/
    	public string getFullName; 
    	{
    	return fullName;
    	}
    	public double getTotalQuizScore; 
    	{
    	return totalQuizScore;
    	}
    	public int getNumQuizzesTaken; 
    	{
    	return numQuizzesTaken;
    	}
     
    	System.out.println("Ben Scanlan";
     
    }

    Have a close look at this line:

    return (int); numQuizzesTaken;

    See anything out of place?

    As an aside, why are you casting an int to an int? Isn't that bit redundant and repetitive?

    Your coding is a little hard to read.... I see your constructor and accessor methods, but where are you mutator methods?
    this makes no sense:
    public double qScore () {
    return (double) totalQuizScore / (int) numQuizzesTaken;
    }
    public int qTaken;
    return (int); numQuizzesTaken;
    }
    in terms of data types I'm talking about and (double), (int) is not needed...

    Please use [code=java] before your code and [/code] after your code to keep the formatting and make pretty colors.



    What is Name supposed to be in the constructor? Perhaps you meant lname?


    In the line:
    return (double) totalQuizScore / (int) numQuizzesTaken;
    ...specifying (double) is useful in getting the correct average but the use of (int) on an int is unnecessary


    In the line:
    public int qTaken;
    ...the method's syntax is incorrect. Here is a basic template for a method followed by an example you can look at. 4 of the methods in the posted code have the same problem.
    accessModifier returnType methodName(param1Type param1Name, param2Type param2Name) {
       param1Name someWorkWith param2Name
       return valueOfReturnType;
    }
    /** Returns the result of multiplying the factors, a fairly useless method commonly used as an example.
    *@param factor1 The first factor to be multiplied.
    *@param factor2 The second factor to be multiplied.
    *@return The result of multiplying factor1 and factor2.
    */
    public static int productOf(int factor1, int factor2) {
       int result = 0;
       result = factor1 * factor2;
       return result;
       //return factor1 * factor2;  //shorthand version
    }



    string is not the same as String in java source code.



    There is a closing bracket missing from the end of the toString method



    The line:
    System.out.println("Ben Scanlan";
    ...seems to be missing something
