Solution 1

foreach( object obj in eleven)
Console.WriteLine("year 11: Name: {0}, School: {1}, Gender: {2}" ,name, school, gender);

for each obj in the queue, you print something that is not related to the queue.

Learn to indent properly your code, it show its structure and it helps reading and understanding. It also helps spotting structures mistakes.
<pre>using System;
using System.Collections;
using System.Collections.Generic;
class MainClass {
    public static void Main (string[] args) {
        Queue eleven = new Queue();
        Queue twelve = new Queue();
        Queue others = new Queue();
        string name;
        string school;
        string gender;
        string year;
        int intVal;
        while(true)
        {
            Console.WriteLine("Name?");
            name = Console.ReadLine();
            Console.WriteLine("School");
            school = Console.ReadLine();
            Console.WriteLine("Gender");
            gender = Console.ReadLine();
            Console.WriteLine("Year");
            year= Console.ReadLine();
            intVal = Convert.ToInt32(year);
            if (intVal > 10 && intVal <= 11)
            {
                eleven.Enqueue(intVal);

Professional programmer's editors have this feature and others ones such as parenthesis matching and syntax highlighting.

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
