How to score a U.S. history practice exam

According to this site called “4dog”, you can get 50/80 MC right, score a very low 4 on the DBQ and the two essays AND still get a 4 on the exam. Is this accurate?</p>

According to CB charts you can get a 5 if you correctly answer 62 percent of the questions. So that means 52 of 80 MC’s and 6s on the essays. A 50 percent will get you a low 4. Of course a 4 is a 4 is a 4.</p>
