Hi Aiman,

Please help me with the questions/answers - I need confirmation by someone who has taken the test recently. retard

I'll sit this test tomorrow. paranoid

Just for little piece of mind: Are you 100% positive that these will be the questions tomorrow? cool

Thanks in advance.

Regards,

PropaGandalf
