Currently I'm a full time employee with the potential to improve myself. I've enrolled in a Master's degree program that will require me to take classes during working hours. For example, I will begin work at 8 AM, head to a lecture at 9 AM, then return to work at 11 AM and work until 5 PM. Lectures will be held every day including weekends.
I work in the IT field which occasionally requires me to stay late and work into the night. Work emergencies and exams will also impact my schedule. I think I'll be overloading myself but I will not get such another opportunity like this easily.
Are there any tips or productivity boosts that may help me in this situation? Is there any scientific research related to this topic - managing/balancing work and school? Are there any proven techniques that can help?
