There really isn�t a shortcut but the good news is that the UCAS website is much easier to search than the book. www.ucas.com.
http://www.ucas.com/getting/before/what.html#1 has guidance that might help.
Or why not phone UCAS up for advice? It also looks like they also have a �15 Centigrade option which will help you make your choice.
Your grades aren�t very high and don�t naturally suggest you�d be a good match for a degree in business and finance, so it�s worth getting some advice.
