Four easy steps to e-learning

Step 1: Find a course

You can buy one or more courses online for yourself or others and, whether you know what you’d like to study or would simply like to browse, finding a course is easy.

Here are some ways you can quickly find the information you need:

  • Search for a course using search box
  • Click "courses" on the top navigation. This page will show a complete list of courses, ordered by our best sellers and new releases
  • Browse courses by category, for example Safeguarding

Step 2: Buy the course

When you've found the course you want simply click on “Add to basket”. You can then continue shopping or check out and make a secure payment via the PayPal payment screen. This allows you to pay with most popular credit or debit cards or your PayPal account, and receive your receipt by email.

All our payments are dealt with by PayPal; one of the world’s most well-known payment providers – Great Britain’s no 1 preferred online and mobile payment method, so you can be sure that your payment will be safe and secure. Here at Virtual College we never even get to see your credit card details!

Once your purchase has gone through you will be able to continue to a login screen. Enter your name and create a password if prompted. This will log you into our Learning Management System (LMS) where you will be able to take the course or allocate it to other people.

You can purchase more than 10 courses online, however if you wish to purchase more than 10 courses, and you would like to be invoiced in advance, you can e-mail us on or contact our sales team on 01943 885 085.

Step 3: Take the course

For the best possible internet browser experience we recommend you use Google Chrome, Microsoft Edge, Internet Explorer 11 or Firefox.

You will get a better learner experience if you have sound enabled. Most computers come with built-in speakers, but the narration will generally be written in text on the screen for you to read if you don't have sound turned on.

The course is interactive and you may need to click on parts of the screen before you can advance. This will be obvious as the narration and text will tell you what to do or the links will pulse and flash. The system will remember where you left off and take you back there, but you can go over any part of it as many times as you want to and take as long as you want.

You can write your own notes for the course and print them off or simply store them to access later any time you view your course.

When you get to the end, you will be presented with an assessment to check your understanding. Don't worry; in most cases you can take this assessment three times at no extra cost, and we have policies and procedures in place for adding further attempts.

Step 4: Your certificate

You will be able to print your own certificate at the end of the course.

Some courses also include the option of a high-quality posted certificate, for example our Level 2 Food Safety and Hygiene courses.
