AP Chemistry Tutoring Online

Why an Advanced Placement Chemistry course?

  • The AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first college year.
  • The AP Chemistry course exposes the student to a universe of knowledge that is unexplored at high school.
  • AP Chemistry gives the student a credit for general chemistry during the first college year.
  • AP Chemistry helps the student to register for courses in other fields where general chemistry is a prerequisite.
  • AP Chemistry fulfills the lab science requirement. Outside the U.S., universities in more than 60 countries recognize AP in their admissions processes.

Who can take up an AP chemistry course?

Students who are successfully completed their first course in high school chemistry. It is recommended that students successfully complete a second-year algebra course.

What does a student get from at eTutorWorld?

  • eTutorWorld helps students get 5 credits on their AP scores.
  • Students get an in depth understanding of fundamentals and reasonable competence in dealing with chemical problems.
  • Our AP Chem Tutors help students to think clearly and express their ideas orally and in writing with clarity and logic.
  • Students will develop the required intellectual skills in chemistry.

 

More on AP chemistry…

  • Students in an AP Chemistry course should spend at least five hours a week in individual study outside of the classroom.
  • Calculators or equation tables are not permitted on the multiple-choice section of the AP Chemistry Exam.
    For the last 40 minutes (Part B) of the exam, students will work without calculators on the free-response section.
  • Students will develop the required intellectual skills in chemistry.
