What do you think about that question? You’ve been working very hard for a very long time. Do you have more in you? I have to warn you that medical school and its exams are even more dependent on the ability to memorize facts and retrieve them quickly in exams.
If you couldn’t be a doctor, what else would you be? This may be a good time to give the question serious thought. Is this career for you? If it isn’t, what is? I am so sorry you have had such struggles. You may have a big decision to make now, and that too, will be a struggle. Take the time you need to make it well.
