Certification is essential for many IT roles, but taking the exams can be expensive. Microsoft is currently running a promotion where you can take a certification exam for free a second time if you don't pass the first time around.
Register for a Second Shot voucher code before booking an exam and you'll have the option of taking it again for free. For selected certifications (including several MCSE options), you'll also score 15 per cent off the price of certification exam packs. The promotion runs until May 31 and you can use the voucher for the 15 per cent off option until the end of December; worth signing up if you're thinking about upping your skills this year.
