* One of the 25-minute sections is entirely multiple choice, with 20 questions.

* The other 25-minute section contains 8 multiple choice questions and 10 grid-in questions. The 10 grid-in questions have no penalty for incorrect answers because the student guessing isn't limited.

* The 20-minute section is all multiple choice, with 16 questions.

Notably, the SAT has done away with quantitative comparison questions on the math section, leaving only questions with symbolic or numerical answers.

* New topics include Algebra II and scatter plots. These recent changes have resulted in a shorter, more quantitative exam requiring higher level mathematics courses relative to the previous exam.

**Calculator Use**

With the recent changes to the content of the SAT math section, the need to save time while maintaining accuracy of calculations has led some to use calculator programs during the test. These programs allow students to complete problems faster than would normally be possible when making calculations manually. The use of a graphing calculator is sometimes preferred, especially for geometry problems and questions involving multiple calculations. According to research conducted by the CollegeBoard, performance on the math sections of the exam is associated with the extent of calculator use, with those using calculators on about a third to a half of the items averaging higher scores than those using calculators less frequently. The use of a graphing calculator in mathematics courses, and also becoming familiar with the calculator outside of the classroom, is known to have a positive effect on the performance of students using a graphing calculator during the exam.
