New Chemistry Regents 2026: What Changed and Tips to Prepare
New York introduced a new version of the Chemistry Regents in June 2026. Officially called the Regents Examination in Physical Science: Chemistry, the new exam is based on the New York State P-12 Science Learning Standards and changes how students are asked to apply what they have learned in chemistry.
If you are preparing for the new Chemistry Regents, studying individual formulas and vocabulary terms is still important, but it is no longer enough on its own. Students also need to be comfortable interpreting information, working with data, and applying chemistry concepts to unfamiliar situations.
Here is what students should know about the new Chemistry Regents and how to prepare for it.
What Changed on the New Chemistry Regents?
One of the biggest changes is the use of question clusters.
Instead of every question standing completely on its own, the new exam groups questions around a common situation or set of information. A cluster may give you a passage, graph, diagram, data table, equation, or description of an experiment and then ask several questions based on it.
Some questions are multiple choice, while others require students to construct their own responses.
This means students need to do more than remember chemistry facts. You may need to interpret a graph, identify which information is relevant, perform a calculation, and then explain what your answer means using chemistry concepts.
What Topics Are on the Chemistry Regents?
The new exam is based on the New York State P-12 Science Learning Standards for physical science. Students should be prepared to apply concepts from throughout their chemistry course.
Important areas to review include:
Atomic structure and subatomic particles
Elements and the periodic table
Periodic trends
Electron arrangement
Chemical bonding
Ionic and molecular substances
Chemical reactions
Balancing chemical equations
Conservation of matter
Moles and quantitative relationships
Energy in chemical reactions
Solutions
Acids and bases
Oxidation and reduction
Properties of matter
Intermolecular forces
Equilibrium and reaction behavior
Rather than simply asking for the definition of a concept, the new exam may provide information and ask you to determine which chemistry concept explains what is happening.
That makes understanding why something happens particularly important.
How Do Chemistry Regents Question Clusters Work?
Question clusters give students a common stimulus followed by multiple related questions.
For example, you might receive information about a chemical reaction along with a graph showing how a variable changes during the reaction.
One question could ask you to identify a trend in the graph. Another could require a calculation. A constructed-response question could then ask you to use chemistry principles to explain the results.
The individual questions may test different skills even though they are based on the same information.
When working through a cluster, read the introductory information carefully before answering the questions. Pay attention to units, labels, experimental conditions, and information included in graphs and tables.
Do not assume that every piece of information needs to be used in every question.
Learn How to Use the Chemistry Reference Tables
The Reference Tables for Physical Science: Chemistry are one of the most important resources to become familiar with before the exam.
New York State introduced the 2025 edition of the chemistry reference tables for classroom use during the 2025-2026 school year, and these are the tables used with the new Regents Examination in Physical Science: Chemistry.
The reference tables contain information students can use to answer questions throughout the exam.
However, having the tables available does not help much if you spend several minutes searching for the information you need.
Before exam day, practice using the reference tables while completing chemistry problems. Become familiar with where commonly used equations, constants, periodic information, and other resources are located.
The goal is not necessarily to memorize everything in the booklet. The goal is to know how to quickly find and correctly use the information that is provided.
Practice With the New Question Format
Past Chemistry Regents exams can still be useful for practicing individual chemistry concepts, but students preparing for the new exam should also practice using the new format.
The New York State Education Department provides sample Chemistry Regents question clusters as well as the actual June 2026 Physical Science: Chemistry Regents.
Working through these materials can help you become comfortable with the types of graphs, passages, experimental information, and constructed-response questions you may encounter.
When reviewing a practice exam, do not only check whether your answer was right or wrong.
Ask yourself why you missed the question.
Did you misunderstand the chemistry concept?
Did you use the wrong equation?
Did you overlook information in the question?
Did you misread a graph?
Did you forget a unit?
Identifying the reason behind mistakes makes practice much more useful.
Review the Chemistry Topics You Struggle With Most
Students do not need to spend the same amount of time reviewing every topic.
Start by completing practice questions covering several areas of chemistry. Keep track of which types of questions consistently cause problems.
If atomic structure questions are easy for you but redox questions are difficult, spend more of your study time working on redox.
The same applies to calculations. If you understand a chemistry concept but regularly make mistakes when solving the related math problems, practice the calculations separately until the process becomes familiar.
A targeted study plan is usually more effective than repeatedly reviewing material you already understand.
Practice Explaining Your Answers
Constructed-response questions require students to communicate their reasoning rather than simply select an answer.
Practice explaining chemistry concepts clearly and directly.
When a question asks you to support an answer using evidence, identify the relevant information in the graph, table, experiment, or passage and connect it to the chemistry concept being tested.
Avoid adding unrelated information just to make an answer longer. Focus on answering exactly what the question asks.
Pay Attention to Units and Information in the Question
Small mistakes can turn an otherwise correct solution into an incorrect answer.
When completing calculations, write down the information you are given and identify the units before beginning.
Check your final answer to make sure the unit makes sense.
Graphs and data tables deserve the same attention. Check axis labels, scales, headings, and units before interpreting the data.
These habits are especially important on an exam that asks students to analyze information rather than simply recall facts.
Use Official Chemistry Regents Practice Materials
The New York State Education Department provides several useful resources for students preparing for the exam, including:
The Reference Tables for Physical Science: Chemistry
Sample question clusters
The June 2026 Physical Science: Chemistry Regents
Scoring materials and rating guides
Practicing with official materials gives you the best representation of how New York State actually writes and structures Regents questions.
Start Preparing Before the Week of the Exam
Trying to relearn an entire chemistry course during the final few days before the Regents can quickly become overwhelming.
Instead, divide your review into smaller topics.
You might spend one study session reviewing atomic structure and periodic trends, another reviewing bonding and intermolecular forces, and another practicing chemical reactions and calculations.
As the exam gets closer, begin mixing topics together and completing question clusters or larger sections of practice exams.
This helps prepare you for the real test, where questions will not necessarily appear in the same order that you learned the material in class.
Get Help With Difficult Chemistry Topics
If you repeatedly struggle with the same types of Chemistry Regents questions, additional instruction can help you identify what is causing the problem.
