Dr. Paytakov holds a doctorate degree in Computational Chemistry. Currently Dr. Paytakov teaches Chemistry and Math courses in a Houston area high school. Dr. Paytakov is certified (Chemistry, Math, Physics and Engineering) and designated Exemplary Teacher by TEA.
Dr. Paytakov has extensive experience in preparing students for Chemistry Olympiad and math contests. He led and coached his home country’s (Turkmenistan) International Chemistry Olympiad (IChO) team between the years 2006-2010. His students won multiple Bronze, Silver, and Gold medals in International Chemistry Olympiad and International Mendeleev Chemistry Olympiad. In addition, Dr. Paytakov has coached students to prepare them for AMC8, 10, and AIME contests.
Dr. Paytakov is thrilled to bring his passion and enthusiasm to prepare Momentum Learning students for the chemistry and math contests.
Class Description
This class will prepare students for the upcoming AP Chemistry exam in May. AP Chemistry is an introductory college-level chemistry course. Students cultivate their understanding of chemistry through inquiry-based lab investigations as they explore the four Big Ideas: scale, proportion, and quantity; structure and properties of substances; transformations; and energy.
Homework
Weekly homework will be assigned. It will take approximately 45 – 90 minutes to complete. Both multiple choice questions and free response questions will be assigned. The homework will be graded and the teacher will go over previous week’s selected homework questions at the beginning of each class.
Prerequisite
Students should be currently taking AP Chemistry in school.
How Long Is The AP Chemistry Exam?
The AP Chemistry Exam runs as one of the longest AP exams at 3 hours and 15 minutes. However, this is just the amount of time that will be used to actually answer questions and respond to the material. Including preparation time, breaks, and other potential interludes, expect the AP Chem Exam to last around 4 hours from start to finish.
How Is The AP Chemistry Exam Scored?
Like all other AP exams, the AP Chemistry exam is scored on a scale of 1-5, where 1 represents “No Recommendation” or a failing score, and a 5 represents “Extremely well qualified” or an A+ or A college course grade equivalent. Generally, anywhere from a 3-5 is considered a passing score, although some colleges and universities may be particular and only accept 4s and 5s for credit. It is also curved similar to other AP exams. In the case of AP chem, you will need to get roughly 75% of the questions correct to score a 5.
What’s The Structure Of The Exam?
The AP Chemistry Exam, like many of the other AP exams, is composed of two sections. The multiple choice section and the free response section.
- The multiple choice section is 1 hour and 30 minutes long, 60 questions with 4 choices each, and is worth 50% of your total score. You will not be allowed a calculator for this portion of the exam.
- The free response section is 1 hour and 45 minutes long, 7 questions total (divided into 3 long essay questions worth 10 points each and 4 short answer questions worth 4 points each), and is worth 50% of your total score. You will be allowed a four-function, scientific, or graphing calculator for this portion of the exam.
