Selection Test date

Got a letter in the post this morning:

"Dear Mr Adam,

With reference to your recent application for entry into the Naval Service I am pleased to invite you to attend this office at 10:00 on 20/03/2007 for psychometric testing..."

So far so good, but now it starts getting scary. Looking through the sample questions they sent me, the tests aren't dissimilar to the ones I took for NATS selection (air traffic control) - same format but slightly easier and not so much of a time pressure. The four sections are Reasoning, Verbal Ability, Maths/Mental Arithmetic and Mechanical Comprehension. Time to get revising!

Hopefully the next post with be a positive one, wish me luck...
