You can have a try

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class TestController extends CI_Controller {
    public function __construct() {
        parent::__construct();
        // Load model
        $this->load->model('TestModel');
    }
    public function student(){
        $obj = new TestModel();
        $value = $obj->student_college();
        echo $value;
    }
}
