Quick question regarding R2 exams

I completed 70-410 (non R2) in Jan but I bought a coupon for all 3 last year. Can I complete 411 & 412 and still get MCSA or will I need to do 410 again and make it R2?
Also is the study guide for R2 needed or can I still use the one for non R2? Any recommendations on a good guide?

You won't need to redo 410. It still counts as part of the series, just any exams from here forward have R2 content in them.
Be sure to use R2 prep material.
