If you are feeling frustrated by the time-consuming nature of formatting academic work, perhaps you will be encouraged by a study by LeBlanc et al in PLOS One which found that 14 hours was the median time that published authors of research articles reportedly spent on formatting. You're not alone in thinking that these kinds of details are time-consuming, but they are also an important part of learning to communicate in the medical profession. Your paper for class should not require 14 hours of formatting, but it does take time and attention to detail.
Keep at it, don't give up, and ask for help if you need it.
