AP Chemistry

AP Chemistry Exam Online Coaching in Gurgaon

The AP Chemistry exam is a college-level test designed to assess your understanding of chemistry concepts, problem-solving, and laboratory skills. It has two main sections: Multiple Choice and Free Response. Students have access to a periodic table and a formula/constant sheet for both sections.

AP Chemistry Exam Format

Section Questions Time Calculator Weight
Multiple Choice 60 90 min Not allowed 50%
Free Response 4 short + 3 long 105 min Allowed 50%

The multiple-choice section includes standalone questions and question groups based on data sets. The free-response section allows calculator use and tests more in-depth reasoning and calculations.

Key Question Topics

  • Experimental design and lab analysis

  • Data interpretation and pattern identification

  • Atomic and molecular representations of chemical phenomena

  • Translating between different forms of data

  • Logical problem-solving in chemistry contexts

Scoring the AP Chemistry Exam

  • Multiple Choice: 1 point per correct answer, no penalty for guessing, maximum 60 points

  • Free Response: Short-response questions = 4 points each, long-response = 10 points each, maximum 46 points

  • Convert raw scores to 50-point scale per section, then sum for a final raw score out of 100

  • Use the College Board conversion chart for AP scores (1–5)

Example 2017 Score Conversion

  • 72–100 = 5 (10.1% of students)

  • 58–71 = 4 (16.2%)

  • 42–57 = 3 (26.1%)

  • 27–41 = 2 (26.2%)

  • 0–26 = 1 (21.4%)
