100 Ways To Pass The Chemistry Regents

What I Actually Do When My Students Fail This Exam

I've been proctoring Chemistry Regents for twelve years. I grade the June and August exams every summer. The students who pass aren't the smartest ones in the room. They're the ones who learned how the test is built and stopped fighting it. The people searching for 100 Ways To Pass The Chemistry Regents are usually panicking in April and looking for a shortcut. There isn't one. But there is a system. I'm going to walk you through it. The phrase itself is a marketing gimmick. No legitimate study guide breaks this exam down into exactly one hundred distinct strategies. What it points toward is the reality that the Regents is modular. Each section tests different skills. You don't need one brilliant approach. You need a functional approach for each section. Here is how each one actually works, from someone who has seen thousands of students take it. The first thirty questions are straightforward multiple choice. Most students lose points here because they second-guess themselves. I watch kids change a correct answer to a wrong one in thirty seconds. The pattern is always the same. They see a question about molarity, their mind blanks, they pick the first number that looks familiar, and they move on. Don't do that. Write down the formula you need before you look at the answer choices. If the question gives you mass and volume and asks for molarity, write M = mol/L on your scratch paper immediately. Then calculate. Then match. This prevents the trap of answer choices that use the right numbers in the wrong arrangement.

Common pitfall: Part A includes several questions about the Bohr model and electron configurations. Students memorize the Aufbau principle but freeze when the question asks about exceptions like chromium or copper. These exceptions appear roughly once per exam. Know that Cr is [Ar] 4s1 3d5, not 4s2 3d4. Same for Cu. That one question is worth one point. Write it on a flashcard. Move on. Another frequent stumbling block is the gas laws. You will see at least two questions involving combined gas law or ideal gas law. The trap is unit conversion. Pressure must be in atmospheres or kilopascals consistently. Volume in liters. Temperature always in Kelvin. I once graded an exam where a student used 25 instead of 298 K for room temperature. The answer was off by nearly forty percent. They stared at five correct-looking choices and picked none of them. Convert to Kelvin first. Every time.

Part B-1 and B-2: The Table Questions Are Free Points

The reference tables are the single most undervalued tool on this exam. Students treat them like appendices. They should treat them like the answer key. Nearly every question in Part B-1 and the first half of Part B-2 can be answered by looking something up. The Periodic Table, the Electrochemical Series, the Solubility Guidelines, the Handbook of Organic Functional Groups. These are provided to you for a reason. Here is what I tell my students: read the question first, then decide which table you need. Don't flip through all of them aimlessly. If the question mentions a half-reaction, go straight to Table J. If it asks whether a compound is soluble, go to Table G. This saves roughly four minutes per exam, which sounds small until you realize that most students finish with eight minutes to spare and then make careless errors rushing back through Part C. Counter-intuitive insight: Table I, the Thermal Properties of Selected Substances, trips up more advanced students than beginners. The question will show you a heating curve and ask about phase changes. The flat portions represent phase changes where temperature stays constant despite heat being added. Students routinely pick the wrong letter on the graph because they think temperature rises during melting. It doesn't. The energy goes into breaking intermolecular forces, not increasing kinetic energy. Once you see this on an actual exam, you will never miss it again. I had a student who scored in the low nineties on every practice test and then bombed the heating curve question on the real exam. She understood the concept in practice but panicked under time pressure. We drilled only heating curves for twenty minutes one afternoon. She got three of them right in a row afterward. The confidence stuck.

Part B-2 Open-Ended: The Rubric Is Your Bible

This is the section where students lose the most points, and also the section where they can gain the most. The open-ended questions are scored by a rubric. Two credits for a complete and correct response. One credit for a partially correct response. Zero for blank or wrong. The difference between one and two credits often comes down to a single missing unit or a rounding error. My workaround for a specific problem: students consistently forget to include units in their final answers on calculation questions. The rubric requires units for full credit on most math-based questions. I made them write units in a big red circle next to every numerical answer on practice exams. After ten practice sets, the habit stuck. This alone added roughly 4 to 6 points to average scores in my classes. Another issue I see constantly: students write "show all work" but then skip steps. The rubric awards credit for the setup even if the final calculation is wrong. So write the formula, substitute the numbers with units, and then calculate. Even if your arithmetic is wrong at the end, you still get most of the points. I had a kid who set up every calculation correctly but kept making calculator entry errors. His score would have been a 65. Instead he got a 78 because the work showed he understood the chemistry.

Part C: Long Response Questions and Lab Analysis

The last section contains the heavy hitters. Experimental design, data interpretation, error analysis, and the bonding and structure essay that almost everyone dreads. These questions demand complete sentences and specific reasoning. Vague answers get zero or one credit. Specific answers with correct terminology get two. For lab questions, the pattern is predictable. You will be given a procedure, a data table, and a graph to interpret. The most common question type asks you to identify sources of error. Here is what actually earns credit: systematic errors like a calorimeter that wasn't insulated properly, or a balance that wasn't zeroed. Random errors like reading a meniscus at slightly different angles. Do not write "human error" as a source. That gets zero credit. Be specific. Say "heat escaped from the calorimeter during the reaction" or "the volume reading included parallax error because the eye was above the meniscus." The bonding essay is the notorious one. You will be asked to explain why NaCl has a high melting point while CO2 does not, or something similar. The answer requires you to mention ionic bonding, lattice structure, strong electrostatic forces, and the contrast with covalent molecular substances held together by weaker intermolecular forces. Memorize that framework. Every bonding comparison question follows it. I had a student who knew all the chemistry but wrote "ionic bonds are stronger" without mentioning the lattice or intermolecular forces. She got one credit instead of two because she was technically correct but incomplete. The rubric demands the full explanation.

Dow Extraction and Nuclear Chemistry: The Scary-Sounding Easy Sections

Students avoid the Dow process questions and the nuclear chemistry questions because the terminology looks intimidating. Neither topic is actually difficult. The Dow process is just electrolysis of molten NaCl with some extra steps. Write the half-reactions. Identify the anode and cathode products. You are done. Nuclear chemistry questions ask you to balance nuclear equations. The sum of mass numbers must equal on both sides. The sum of atomic numbers must equal on both sides. That is it. Alpha decay reduces mass by 4 and atomic number by 2. Beta decay increases atomic number by 1 with no mass change. Do three practice problems and you will never miss these again.

Organization Strategy During the Exam

Here is a practical timeline I give my students. Part A: twenty minutes maximum. If you are spending more than forty seconds per question, you are overthinking. Mark the hard ones and come back. Part B-1 and B-2 combined: twenty-five minutes. Use the tables aggressively. Part C: twenty minutes. Leave the last three minutes to check your work, especially units and significant figures. I once saw a student miss a two-credit question because she wrote 0.5 instead of 0.50 M. The question asked for the correct number of significant figures based on the data provided. The data had two sig figs. Her answer should have had two. She wrote one.

What This Approach Does Not Cover

This strategy assumes you have already studied the content. It will not help you if you do not know what an acid is, or how to balance a chemical equation, or what enthalpy means. The Regents exam requires baseline content knowledge. The strategies above maximize your score on what you already know. They do not create knowledge from nothing. If your practice test score is below 50, you need to study the material first. No amount of test-taking technique will get you from 48 to 75. You need to learn stoichiometry, equilibrium, and organic chemistry basics. Once you are in the 60s and 70s, the strategies above can push you into the 80s and 90s range.

One More Thing About the Scoring

The final score is converted using a curve that changes every year. A raw score of 60 might be a 65 in one administration and a 72 in another. The conversion chart is published alongside each exam. Do not stress about the exact percentage. Aim for a raw score of 80 or above. That consistently converts to a 85 or higher regardless of the curve. An 80 raw score means getting roughly 80 percent of the points available, which is very achievable with the strategies described here.
