Hi gmat20192,
You bring up a very good point. I agree that creating an old-fashioned
error log using Excel or Word can be can be incredibly time-consuming. However, error logs do help you keep track of your weaknesses in an organized fashion. Thus, if you find that you are spending too much time maintaining your
error log, consider using a self-study course that tracks your stats for you and provides a personalized
error log with detailed analytics.
Feel free to reach out with further questions.
