Praxis Chemistry Preparation & Registration
Preparing for the Praxis Chemistry exam is simple with these brief but in-depth video lessons. The chapters align with all of the topics on the exam, and the lessons are presented in a way that makes the information clear and enduring. View each lesson's video and quiz yourself on your comprehension of the topics. You can also use the short self-assessment quizzes before watching the video lesson to gauge your current understanding, then check out lessons where you could use improvement. Taking the quizzes not only examines your knowledge level in a topic, but gets you familiar with the types of questions you'll find on the Praxis Chemistry exam.
Registration and payment for the exam can be done online or by mail about a month before the scheduled test date. Late and emergency registration is also available for an additional fee. During registration, you'll need to provide background information on your education and experience, as well as institutions where you'd like to send your score report. When you show up for the exam, you'll need to present your test ticket and photo identification. For paper-based exams, you'll need to bring #2 pencils.
Praxis Chemistry Exam Scoring
The passing score depends on the requirements of your state, though your score report will include whether you met your state's standard. The report will also indicate your score, the range of scores available, and the middle 50% of actual scores for all individuals who took the exam. You'll only be scored on the questions you answered right. Incorrect answers won't reduce your score, so it's recommended that even if you don't know an answer to a question, use methods to eliminate obvious wrong answers and give it your best guess. Your score report will be made available to you online about 2-3 weeks after the test date. You can call in for your scores after 10 business days for an additional fee.
Matter & Energy; Heat, Thermodynamics & Thermochemistry
This section typically consists of 16 questions. Topics in these question discuss the organization and particulate structure of matter, the contrast of physical and chemical properties, energy and matter conservation, and types of energy forms. Lessons in the Matter and Energy, Thermodynamics, and Gasses chapters cover such topics as the states of matter; kinetic, chemical, electrical and nuclear energy; the laws of thermomodynamics; phase diagrams; Dalton's Law of Partial Pressures; and the Ideal Gas Law.
Atomic & Nuclear Structure
There are 10 questions related to atomic and nuclear structure on the exam. Subjects range from the current atomic structure model, the elements' electron configuration, radioactivity and electronic energy. You'll find lessons about early atomic theories; isotopes; wave parameters; alpha and beta particles and gamma radiation; balancing nuclear equations; mass-energy conversion; and applications of nuclear chemistry in the Atomic Structure chapter of this course.
Nomenclature; the Mole, Chemical Bonding, & Geometry
The exam's 14 questions on nomenclature ask about inorganic compound chemical formulas and systematic names, as well as common organic compounds and the Mole concept. You'll also find questions about the types and properties of bonds, polar and nonpolar molecules, molecular geometry, and the correlation of bonding and structure with physical properties. The lessons in the Nomenclature and Chemical Composition and Bonding chapters help you prepare for these questions by going over ionic and covalent compounds, hydrates, hydrogen and intramolecular bonding, Lewis Structures and relative bond lengths and strengths.
