Should be doable. Try to fly at least two to three times a week around your work schedule. If the school can't accommodate that, then find another school. You are the customer in this equation.
The biggest thing you can do to help yourself progress through the training is study ahead of each lesson and visualize or "chair fly" procedures/maneuvers/ATC comm etc. This is a common technique for USAF students. I tried to get civ students to do this (with varied success) and when they did it worked well. After each lesson take detailed notes during the debrief and come up with items you'd like to fix on the next lesson. Write it out " the next time I fly I will..." Read the notes of your last few lessons when preparing for your next lesson.
