If you are at all thinking about doing Microsoft Certification exams, now would be a good time. You can buy packs of discounted exam vouchers that includes a second try on any exam you fail.
The free retry (second shot they call it) means you can study less and just go for it. If you fail the first one, at least you know the gist of the exam content, and you know what to study more.
