Best Answer

you can check current users order for new user . if current user has order thats mean he is not new user, otherwise he/she is new user

$customer = Mage::getSingleton('customer/session')->getCustomer();
$email = $customer->getEmail();  
$orderCollection = Mage::getModel(‘sales/order’)->getCollection();
$orderCollection->addFieldToFilter(‘customer_email’, $email);
$newUser =false; 
if(empty(orderCollection->getData()) ){
   $newUser =true; 
}

You can try with this two Event

customer_save_before
customer_save_after

First of all ,i guess that you have already create customer groups Student,Guest from Admin>Customers>Customer group.

Find details on event and observer here

Model Approach

Step1: trigger an event on basic of customer_save_before

<global>
    <events>
        <customer_save_after>
            <observers>
                <change_customer_group>
                    <type>singleton</type>
                    <class>magento63798/observer</class>
                    <method>ChangeCustomerGroup</method>
                </change_customer_group>
            </observers>
        </customer_save_after>
    </events>
</global>

Step2: Magento Observer Code is below and guess that guest custome group id is 2,Student is 5.

<?php
class Stackexchange_Magento63798_Model_Observer
{
    public function ChangeCustomerGroup(Varien_Event_Observer $observer){

        $customer=$observer->getEvent()->getCustomer();
        Mage::log('My log entry'.$customer->getId(), null, 'Magento63798.log');

        $StudentGroup=5;
        $GuestGroupId=2;
        list($user, $domain) = explode('@',$customer->getEmail());

        if ($domain == 'gmail.com'):
            /* set Customer group as Stiudent */
            $customer->setData('group_id',$StudentGroup);   
        // use gmail
        else:
            $customer->setData('group_id',$GuestGroupId);   
        endif;


    }

Magento – How to get the raw customer password when customer is already registered

You cannot get the customer's plain text password after they have registered and logged in. That would be a huge security problem.

You should rethink whatever you have in mind and find a way to do it that doesn't require the password.
