Mathematica
To obtain a license to install on your PC/Mac follow the instructions below:
If you don't have a Wolfram account you will need to create one, with your University email address (@cam.ac.uk or @SOMETHING.cam.ac.uk).
Once you have an account click on the Wolfram User Portal again, and this time you will get an online form to fill in and submit.
You will then be taken to a screen that says Your Activation Key Has Been Created and you will see the activation key and your details.
Go to the Product Summary Page, select the platform (windows, linux or mac) and download the install files for Mathmatica.
Once downloaded, install Mathematica and enter your licence key when prompted.
