You need to check your syllabus to see how your professor has weighted each exam. and what their grading policy is. Some profs will drop your lowest grade; others will overweight the final so it’s worth more than any single midterm; still others will have a really huge curve at the end of the class. So whether you’ll be able to recover and get an A is depends on that syllabus & the professor’s grading rubric. There’s no way for us to know.
BUT… don’t freak out. Take a deep breath and do better next time. One C or even a D or F is not going to keep you out of med school.
But college is big step up from high school–and it’s only going to get harder from here. You need to improve your game if you want to be competitive. Consider going to the academic support center at your college and get some help with test taking skills and writing skills so you’ll be better prepared for the amount of essay writing on the next exam.
One bit advice my older D gave her sister when she started college: NEVER leave an answer blank. Write something down. Even if it’s mostly wrong or terribly incomplete, you’ll still get some partial credit and every point helps.
At the beginning of the exam, don’t dive right in. Take a moment to look through the entire exam so you’ll know how long it is. Answer the questions you have down cold first., but don’t go overboard with elaborate answers. Answer the question, but don’t add in unnecessary details. Then go on to the more challenging questions, leaving the most difficult or any you aren’t sure how to answer for last. IOW, don’t go through the exam sequentially. Keep your eye on the time. Don’t spend too much time on any one questions. Truncate your answers if necessary and keep moving on so that you have written down something for every single questions.
