Getting certified in the UK

My company are happy to pay for me to get certified to Oracle OCP level
- and have booked all four required courses for me. I have been on the
first course Oracle9i:SQL.

I would like to purchase some practice tests before I do the exam. On the Oracle website Self Test Software is recommended - and my company are happy to buy it for me - but would like to purchase it in the standard way - by raising a purchase order and buying CD-ROM. Unfortunately this seems to be impossible in the UK - I have been in contact with both Oracle UK and STS and neither can sell a CD in the UK.

Does anyone know if there is any way I can get hold of this CD in the UK
- or are there any alternatives that I could use?

TIA
