Overview of the Chemistry Regents Exam
The Chemistry Regents exam is designed to evaluate students' knowledge and skills in chemistry, covering a wide range of topics. The exam is typically divided into two main parts:
1. Part A: Multiple-choice questions that test students’ basic understanding of chemical principles.
2. Part B: Constructed-response questions that require students to demonstrate their problem-solving skills and apply their knowledge to specific scenarios.
The exam is scored on a scale of 0 to 100, with a passing score typically set at 65. Each year, students take the exam in January, June, and August, with the January exam being particularly important as it often serves as a final assessment before students graduate or proceed to advanced courses.
