If these two conditions meets then, display information page(id-12) Course1.

I am trying to do it in catalog/controller/information.php

$id = $this->customer->getGroupId();
if ((!$this->customer->isLogged()) && ($information_id == 12) && ($id==2)) {
$this->response->redirect($this->url->link('account/account', '', 'SSL'));

}

But without login also this page is visible .

$group_id = $this->customer->isLogged() ? $this->customer->getGroupId() : 0;
if ($information_id == 12 && $group_id != 2) {
    $this->response->redirect($this->url->link('account/account', '', 'SSL'));
}
