How can you avoid burnout? First and foremost, set reasonable goals. I’m sure you’ve read those words elsewhere, probably dozens of times, but they bear repeating, especially when it comes to unpleasant tasks that need to be done over long periods of time.
Can you improve your score 100 points in two weeks? Probably not. Can you improve your score 100 points over two months? With steady work, that’s a reasonable goal. Will you spend two hours a day working on the GMAT, every day, without fail, for eight weeks? No. Could you spend 7-10 hours per week, including at least 15 minutes per day?
I hope so.
