Hi Sam, thanks for the response.
Are you sure my highest would be Bachelors, in the Help menu for that section, the description given for two or more certificates or degrees is:
A three-year or more certificate, diploma or degree combined with any other certificate, diploma or degree of one-year or longer.
Which is exactly what I have, I have a bachelors that is verified by IQAS as a 4 year degree, and a diploma that is verified as a One-year degree, diploma or certificate. So I was thinking that I should put two or more degrees as my highest, since the option is present.
