Need Help understanding AP Physics C Mechanics score calculator

I'm a bit confused with how the scoring system works for AP Physics C Mechanics. Could any of you explain this to me? Also, what level of understanding or score would you suggest for me to aim to feel confident about getting a 5?

The scoring process for AP Physics C Mechanics commences by scoring your multiple-choice and free-response sections, which are then combined to form a composite score. This composite score is then translated into the 5-point AP score.

The multiple-choice section makes up 50% of your total score, while the free-response section also accounts for 50%. There are 35 multiple-choice questions and 3 free-response questions.

Each multiple-choice question you correctly answer earns you one point. There's no penalty for incorrect answers or blank answers on the AP exam, so it's in your best interest to at least guess on every question.

The free-response section's scoring is a bit more nuanced. Each free-response question is graded on a point system where you can earn points for each part of the question you solve correctly. These points add up to your total score for each free-response question, and those results are then combined for your total free-response section score.

Now regarding aiming for a 5, it's important to note that the exact percentage of correct answers needed for a 5 varies slightly from year to year, but generally, achieving a composite score of around 60% or higher can reliably earn you a 5 on this exam. To increase your chances of getting a 5, I'd recommend thorough exam preparation, including reviewing key concepts and practicing with past exams to develop an effective test-taking strategy and pacing.

Remember, it's not necessarily about aiming for perfection, but instead consistently demonstrating a solid understanding of the concepts covered on the exam.
