Plugin settings not saving

I’m having a devil of a time getting my plugin settings to save. I’ve gone through the code so many times I have to think I’ve simply missed something. I’m following the Setting API, but any changes I make on the plugin settings page don’t save. What did I miss?

function __construct() {
self::$instance = $this;

//  Add "Settings" link to plugin page
add_filter( 'plugin_action_links_' . plugin_basename( __FILE__ ) , array( $this, 'settings_link' ) );

// Creates the CEMB Seminar submenu
add_action( 'admin_menu', array( $this, 'add_menu' ) );

// Register and define the settings
add_action( 'admin_init', array( $this, 'settings_init' ) );

} // End of __construct()


/***** Menus *****/

//  Add "Settings" link to plugin page
function settings_link( $links ) {
    $settings_link = sprintf( '<a href="%s">%s</a>', admin_url( 'options-general.php?page=cemb-seminar' ), __( 'Settings' ) );
    array_unshift( $links, $settings_link );
    return $links;
}

// Creates the CEMB Seminar submenu
function add_menu() {
    add_submenu_page( 
        'edit.php?post_type=cemb_seminar', 
        __( 'Course Requirements' ), 
        __( 'Course Requirements' ), 
        'manage_options', 
        'cemb-seminar', 
        array( $this, 'settings_page' )
    );
}

the problem is you keep resting the values here:

 $options = array(
        'cemb_seminar_seminars_college' => '0',
        'cemb_seminar_showcases_college' => '0',
        'cemb_seminar_writers_college' > '0',
        'cemb_seminar_aet_college' => '0',
        'cemb_seminar_mbu_college' => '0',
        'cemb_seminar_eis_college' => '0',
        'cemb_seminar_sng_college' => '0',
    );
    update_option( 'cemb_seminar_options', $options );

change it to

$options = get_option('cemb_seminar_options');
if ($options === false){
$options = array(
            'cemb_seminar_seminars_college' => '0',
            'cemb_seminar_showcases_college' => '0',
            'cemb_seminar_writers_college' > '0',
            'cemb_seminar_aet_college' => '0',
            'cemb_seminar_mbu_college' => '0',
            'cemb_seminar_eis_college' => '0',
            'cemb_seminar_sng_college' => '0',
        );
        update_option( 'cemb_seminar_options', $options );
}

so it will only run if ‘cemb_seminar_options’ is not set in the database
