Hi,
I checked with a colleague at Microsoft Learning. Unfortunately, the 3-for-1 Developer Certification Exam offer cannot be combined with the Second Shot Offer.
Here are a couple of resources to help you prepare for your exams.
Developer Study Groups
Microsoft Virtual Academy
Good luck with the exams. They are very challenging but fair.
Thanks,
