1. Match the exact Chemistry exam

The new Physical Science: Chemistry (NYSP12SLS) examination began in June 2026. The legacy Physical Setting/Chemistry examination continues through June 2027 in NYSED’s transition schedule. Match the full title and date on your paper. NYSED implementation schedule.

Supported exam charts and raw-credit limits
Exam title	Administration	Maximum earned raw credits
Physical Science: Chemistry (NYSP12SLS)	August 2026	48
Physical Science: Chemistry (NYSP12SLS)	June 2026	50
Physical Setting/Chemistry	August 2026	85
Physical Setting/Chemistry	June 2026	85
Physical Setting/Chemistry	January 2026	85
Physical Setting/Chemistry	June 2025	85

The new exam’s maximum varies: June 2026 uses 50 raw credits; August 2026 uses 48. Those are the maxima on their published conversion charts. Do not substitute the number of questions for the number of available credits.

Legacy section limits

Physical Setting/Chemistry section allocation
Section	Question numbers	Maximum credits
Part A	1–30	30
Part B-1	31–50	20
Part B-2	51–65	15
Part C	66–85	20
Total	Whole legacy paper	85

The four section fields apply to the legacy 85-credit format. For the new exam, enter total earned raw credits instead. Use the official key and rating guide for your specific paper. NYSED administration directions.

2. How the score conversion works

Mark the paper with its matching answer key and rating guide, add the earned credits, then look up that integer in the same administration’s conversion chart. The scale score is out of 100. It is not a direct percentage or an estimated line between a few anchor scores.

Written responses may earn rubric-based credit for evidence, explanations, units, calculations or diagrams. Follow the particular question’s guide; a correct final number alone does not always demonstrate all required work. New exam rating guide · Legacy June 2026 rating guide.

June 2026 legacy practice papers: NYSED corrected the multiple-choice scoring key on 24 June 2026. Use the version marked “Updated, 6/24/2026” before calculating your raw credits. Read the official correction notice.

Worked example: January 2026 legacy exam

25 + 15 + 10 + 10 = 60

Those section scores convert to 71 on the January 2026 chart. On this same chart, raw 10 converts to 25, raw 68 to 78, and raw 80 to 91. Verify the January 2026 rows.

Worked example: new exam

In both supported new-exam charts, 21 raw credits convert to 65. To reach a scale score of 85, June 2026 requires 38 raw credits, while August 2026 requires 36. Choose the administration before interpreting a raw total.

65 is the common Regents passing benchmark. An 85 is an exam-score benchmark used in mastery requirements; one Chemistry score does not award a diploma endorsement.

Mastery in Science requires a Regents diploma with advanced designation and normally scores of 85 or better on three science Regents examinations. NYSED also describes alternatives involving two qualifying exam scores and one granted exemption, or one qualifying exam score and qualifying course grades with two granted exemptions. Your school must check the applicable rules against your complete record. NYSED endorsements and seals.

This calculator does not determine eligibility for a local diploma, safety net, appeal, exemption or other graduation pathway. A result below 65 does not settle those questions. Consult your school counselor. NYSED graduation FAQ.

5. Calculator rules, reference tables and lab requirements

Equipment depends on the full exam title
Exam	Permitted calculator	Reference-table edition
Physical Setting/Chemistry · legacy	Four-function or scientific. ALL graphing calculators are prohibited.	2011 Physical Setting/Chemistry
Physical Science: Chemistry · NYSP12SLS	Scientific or graphing, subject to NYSED restrictions.	2025 Physical Science: Chemistry

For the new exam, calculators must not have symbol-manipulation capabilities or infrared communication. Programmed memory must be cleared, reset or disabled; a password-protected calculator that cannot be cleared is not permitted. Operating manuals and instruction cards are not allowed during the examination. Check the rules for your administration with your teacher. NYSED calculator requirements.

Open the 2025 Chemistry reference tables · NYSED reference-table editions. Match the edition to the exam, rather than simply choosing the newest file for a legacy paper.

NYSED requires 1,200 minutes of laboratory experience with satisfactory documented reports, in addition to classroom instruction. Current guidance allows hands-on and simulated experiences. For the new course, successful completion of the required investigations is also part of exam admission. Do not add investigation performance as bonus credits to this written-test total. Confirm completion with your teacher. Science laboratory guidance · New-course investigations requirements.

6. Focused Chemistry revision notes

Use these reminders to diagnose missed practice questions. They are a concise review, not a complete syllabus or a prediction of exam topic weights.

Atomic structure and the periodic table

Atomic number identifies the number of protons. Isotopes have the same proton count but different neutron counts. For an ion, account for lost or gained electrons when interpreting charge. Use the reference table’s electron configurations, oxidation states and trends; avoid assuming every element in a group behaves identically.

Bonding and particle attractions

Distinguish ionic, covalent and metallic bonding from attractions between particles. Explain properties using the particles and forces present. Molecular polarity depends on both bond polarity and geometry; polar bonds alone do not establish that the whole molecule is polar.

Moles and balanced equations

Use molar mass consistently to convert mass to amount of substance. Balance equations by changing coefficients, never subscripts. The coefficients give ratios of amounts of substance, not arbitrary ratios of masses.

n = \frac{m}{M}

Solutions and concentration

Molar concentration uses the amount of dissolved solute and the solution volume in litres. For solubility questions, compare the stated amount and temperature with the relevant curve, and distinguish a supersaturated solution from a saturated solution with undissolved solid.

c = \frac{n}{V}

Mass composition

Identify the part and the whole before calculating a mass percentage. In a compound, use the total contribution of the element in one formula unit relative to the compound’s molar mass.

mass percent = \frac{mass of part}{mass of whole} \times 100 %

Heat and temperature

For heating or cooling without a phase change, use a consistent mass, specific heat capacity and temperature change. A phase change needs the appropriate latent-heat relationship instead. Temperature measures a different property from the total thermal energy transferred.

q = m c Δ T

Gases

For a fixed amount of gas under the ideal-gas approximation, relate pressure, volume and absolute temperature. Convert temperatures to kelvins and keep pressure and volume units consistent between states.

\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}

Reaction rates and equilibrium

A catalyst provides an alternative reaction pathway and speeds up approach to equilibrium. At a fixed temperature it does not change the equilibrium constant or the equilibrium composition. Use the reaction and the actual disturbance to predict a shift.

Acids, bases and redox

Use the acid-base model requested in the question and compare acid strength separately from concentration. Oxidation is electron loss; reduction is electron gain. Check that atoms and charge balance in a redox equation. Use the correct reference tables for reduction and oxidation information.

Organic and nuclear chemistry

Identify functional groups from structure rather than the name alone. In nuclear equations, conserve mass number and atomic number; radioactive decay changes nuclei, while ordinary chemical reactions rearrange electrons and bonds.

Continue with the Chemistry Regents preparation guide and the official released papers for your course.

7. Turn a practice score into a study plan

Choose a released paper with the same full exam title as your course.
Use its matching reference tables, permitted calculator, answer key and rating guide.
Record earned credits. For each missed item, identify the concept, evidence, calculation, unit or explanation that lost credit.
Convert with that paper’s chart. Choose a scale-score target to see the minimum raw total and the additional credits needed on this chart.
Practise the missed skill, then mark a fresh question. Recheck an unfamiliar table or unit before substituting numbers.

A gain on a past paper does not guarantee the same scale score on a future administration. The tool does not mark written responses.

8. Frequently asked questions

Which Chemistry exam should I select?

Match the full title and administration on the paper. Physical Science: Chemistry (NYSP12SLS) is the new exam; Physical Setting/Chemistry is the legacy exam. Their charts are not interchangeable.

Is the new Chemistry exam always out of 50 raw credits?

No. The published June 2026 chart has a maximum of 50; August 2026 has a maximum of 48. Select the matching chart before entering total raw credits.

What are the legacy section limits?

Part A has 30 credits, Part B-1 has 20, Part B-2 has 15 and Part C has 20, for 85 total. Use total-credit entry for the new exam.

Does the calculator use a predicted curve?

No. It looks up every integer raw score in the selected published NYSED chart. It does not interpolate between anchor points or apply a plus-or-minus-one buffer. Practice results still depend on accurate marking.

What do 60, 68 and 80 raw credits mean in January 2026?

On the January 2026 legacy chart, they convert to 71, 78 and 91 respectively. Raw 10 converts to 25. Use the matching chart for other administrations.

What raw score reaches 65?

In the six supported charts, the minimum is 50 for each legacy paper and 21 for each new-exam paper. These values apply only to those listed charts.

Can I use a graphing calculator?

Not for legacy Physical Setting/Chemistry: all graphing calculators are prohibited. The new Physical Science: Chemistry exam allows scientific or graphing calculators subject to NYSED restrictions, including no symbol manipulation and cleared, reset or disabled programmed memory.

Does 85 earn Mastery in Science?

A single score does not award the endorsement. Advanced-designation diploma requirements and the applicable combination of science exam scores or granted exemptions must also be satisfied. Your school determines eligibility.

Do investigations add bonus points?

No. Successful completion of the required new-course investigations is part of exam admission. Do not add investigation performance to the written-test raw total.

Can I enter decimals or negative credits?

No. Enter a whole number within the selected exam’s maximum. Zero is valid. Each legacy section also has its own maximum.

Can I use this for a future or unlisted exam?

Only the listed published charts are supported. The tool does not assign an old curve to an unlisted exam. Use its own official conversion chart when available.

Can I download my result?

Yes. A successful conversion enables CSV download with the selected chart, source, raw and scale scores, target and limitations. Changing inputs requires a fresh conversion before another download.

Who maintains this calculator?

NUM8ERS checked the six linked charts and the method on 26 October 2026. This independent practice tool is not affiliated with NYSED and does not replace official school scoring.

Official sources and method review

Maintainer: NUM8ERS · reviewed 26 October 2026. Every included score is an exact lookup from the linked NYSED file. Choose the same administration in the calculator and source table.

I had a great experience learning math with Ms. Mavish. She explains complex topics in a very clear and simple way, which made it easier for me to understand and enjoy the subject. Her patience and dedication really stood out, and she always made sure that everyone in the class was keeping up. I especially appreciated how approachable she was — I never felt afraid to ask questions, and she was always willing to help. Thanks to her teaching, my confidence in math has grown a lot. I’m really thankful for the effort she puts into every lesson!
