I have recently found myself having to cut back on expenses

One of these expenses was my exam costs. I was all set to write my 70-297 exam not too long ago when $$$ got tight and I had delay/cancel my booking. Now as I work my way to get back on my feet, I'm still studying, but I've started to become stale with material and started looking/reading citrix doc's and have become interested with the 1Y0-259 exam.
Could this hurt me if while I sort out my finances that I'm studying 2 different subjects?
