Are 55 credits doable in 1 semester

[allvia]

The more you can transfer in before you begin the better; even if it means you push back your enrollment by a month. The less credits you need to earn in the term the more likely you'll be able to active the goal.  It is far more realistic to complete 30 credits in the term than 55. I'm sure if you post which WGU degree, and what you have left to complete for the program people here will have suggestions for you.
