Admin qualifications

[CAJ1]

I work as an administrator. I have done a NVQ Level 3 in Administration, essential skills in number and communication, a certificate in business etc, a course in minute taking and being an effective administrator. I tried to do an A Level in Business Studies from home but found the accounts part too much for me to understand and my tutor was rubbish so I gave up. I applied to do GCSE Business Studies at evening classes but it got cancelled yesterday as I was the only one signed up for it! I still want to learn but don't know what course would be suitable, I would prefer to do one from home - does anyone know what I can do next?

TIA
