I am currently working 40+ hours a week plus I am getting my MBA. I go to class twice a week from 6:15-9 PM every Tuesday/ Thursday. The best advice I can give is work on your time management. When you get home, leave work at the door. When your home focus a few hours on studying, if you can. You wouldn’t believe the amount of studying you can get done if focus for 2-3 hours at a time. By 8 PM you’ll feel like you’ve accomplished so much.
