How many reading questions do i need to get correct to go up from a 620 to a 700?

To determine how many more reading questions you need to get correct to increase your score from a 620 to a 700 on the reading section of a standardized test like the SAT, you would need to refer to the specific scoring guidelines of the test. Generally, the SAT has a complex scoring model where the raw score (the number of questions answered correctly) is converted into the scaled score through a process called equating. This process adjusts for slight differences in difficulty between various versions of the test.

Unfortunately, without specific information on the exact test version and its scoring chart, we can't determine the exact number of questions you need to answer correctly to achieve a specific scaled score increase.

However, in general terms, each question on the SAT reading section is typically worth approximately 10 points on the scaled score, but this is not a strict rule as the exact value can vary. To improve by 80 points (going from 620 to 700) you may need to answer around 8 more questions correctly, assuming each question impacts your score equally, which in practice may not be the case due to the aforementioned equating process.

It’s important to review the scoring charts provided from the College Board or the specific test handbook and practice tests in order to get a clearer understanding of how many questions may be needed to increase your score by 80 points.
