Dihaz,
The GPI link is a pesonal link, click on it and follow the instructions.
As far as the maths questions go, follow the instructions on the 'DEP Candidate Briefing 2010' you were sent. It says:
Verbal and Numerical Tests
Practice leaflets, which explain more about these tests and give examples of the type of questions you will face, are also included with this briefing.
The verbal test examples are shown in the booklet entitled: Why are aptitude tests used? The numerical tests examples are in the Technical Test Battery - Practice Leaflet under Test 6 Numerical Reasoning. Please note that you must practice these without a calculator.
