ACT Hand Scoring Should You Order It

ACT Hand Scoring Should You Order It SAT / ACT Prep Online Guides and Tips Did your ACT scores seem way out of whack? Enough that you think there was an error in the scoring process? It’s possible to get your test rescored manually for a fee. Read on to find out why you might decide to use ACT Score Verification (also known as ACT Hand Scoring) and how you can order it. What Is Hand Scoring? The multiple choice sections on the ACT are scored with scantron machines, which is why there's so much emphasis on filling in the answer sheet accurately with dark marks.Machines may interpret a stray mark as an answer or penalize you because you accidentally skipped a question and bubbled in a string of answers in the wrong spots.If you order score verification, your test will be reviewed again by a human being to see if there was a problem in the original scoring process or if you made an obvious bubbling error that would be apparent to a human grader but not a scantron. ACT score verification is available for both the multiple choice and essay sections of the test (if you did ACT Writing).It’s a $50 fee for the multiple-choice section, $40 for the essay section, or $90 for both.If you're at all familiar withSAT Hand Score Verificationor have ordered it before, you should know thatACT Score Verification differs in one important way.For SAT Hand Scoring, there's the risk tha t your score will go down if mistakes in scoring are found that aren’t in your favor.For the ACT, your score will either stay the same or go up- ordering hand scoring can’t hurt your score, it can only hurt your wallet.If the ACT does find a scoring mistake that works in your favor, your scores will be changed and the fee will be refunded. Special note: In past years, ordering ACT essay score verification meant that your essay was reread and rescored (if your score was higher; otherwise, your score stayed the same). Now, however, getting score verification for your ACT essay only gets you confirmation your essay was scored by two independent graders (or by a third grader if the two scores differed by more than a point in any domain) and that your essay was scanned correctly. When Should You Use Score Verification? Here are a couple of scenarios where you might consider Hand Scoring as a score verification method: Scenario 1: Your Overall Score Was Very Different from What You Expected How different is â€Å"very different†?If you get a score on one or more of your ACT sections that is five or more points lower than the score you consistently earned in practice sessions, you might consider hand scoring. With this much of a discrepancy, it’s likely that something weird happened in the scoring process or you did something on the answer sheet that caused your answers to be read inaccurately. Scenario 2: You Missed Many â€Å"Easy† Questions That You Would Normally Get Right If you look at your score report and notice that you got a bunch of questions wrong in subjects that you usually ace, you might start to question your scores.However, you should consider ordering the Test Information Release, described in my next point, to verify the difficulty level of the questions you missed before jumping to any conclusions. Scenario 3: You’ve Investigated Other Score Verification Options The ACT Test Information Releaseprovides a more comprehensive view of the test. It includes all the questions, a list of your answers, the answer key, scoring instructions, and the writing prompt and scoring rubric along with your scores (if you took the ACT with Writing).You can order the Test Information Release for $20 (per test date). This will either clear up confusion about your scores or verify that something went wrong and you need to order ACT Score Verification (hand scoring). When Should You NOT Use Hand Scoring? You shouldn't jump right to hand scoring if your score is only a little lower than you expected it to be. Say you get your scores back and you did about four points worse than you expected on one or more sections. Do you order hand scoring?I would say that’s the tipping point. A discrepancy between expectations and reality of four points or less is probably not significant enough to indicate an error in scoring. If you're still concerned, you should go ahead and order the Test Information Release so you can understand your scores better.Try not to jump right to blaming the test if you score a couple points lower than you expected- it’s not going to help you learn from your mistakes! The best place to learn is on top of a pile of past mistakes. How to Request Hand Scoring To have your test hand scored, just fill out this form and mail it to the ACT within 12 months of your test date.Include your name (the original one that you wrote on the test), address, and date of birth along withthe ACT ID, testing location, and test date from your original score report. You should also include a check made out to ACT Student Services with the applicable fees for whichever part of the test you want hand scored.Remember, multiple choice is $50, essay is $40, and it’s $90 for both. Mail everything to this address: ACT Student ServicesP.O. Box 414Iowa City, IA 52243-0414 You can also request to be in the room for the hand scoring process for your multiple choice questions (but without access to the test questions) at a location designated by the ACT. If you would like to do this you should mail this request in writing along with everything else, although I would say that unless you are super paranoid about them messing up the scoring again you probably don’t want to bother with it. The ACT says that additional fees apply, but the information they give about it is very vague- you may want to call them to find out more details before you decide to put in a request. The number for ACT Customer Service is 319-337-1270. After you mail your score verification request, you should get a letter back from the ACT in three to five weeks. It will tell you whether your original scores were confirmed or changed due to an error in the original scoring process. If they were changed, you and all your designated colleges will get new score reports free of charge. What's Next? Are you wondering whether you should take the ACT again?

Solubility Definition in Chemistry

Solubility Definition in Chemistry Solubility is defined as  the maximum quantity of a substance that may be dissolved in another. It is the maximum amount of solute that may be dissolved in a solvent  at equilibrium, which produces a saturated solution. When certain conditions are met, additional solute may be dissolved beyond the equilibrium solubility point, which produces a supersaturated solution. Beyond saturation or supersaturation, adding more solute does not increase the concentration of the solution. Instead, the excess solute starts to precipitate out of solution.​ The process of dissolving is termed dissolution. Solubility is not the same property of matter as the rate of solution, which describes how quickly a solute dissolves in a solvent. Neither is solubility the same as the ability of a substance to dissolve another as a result of a chemical reaction. For example, zinc metal dissolves in hydrochloric acid through a displacement reaction that results in zinc ions in solution and the release of hydrogen gas. Zinc ions are soluble in acid. The reaction is not a matter of the solubility of zinc. In familiar cases, a solute is a solid (e.g., sugar, salt) and a solvent is a liquid (e.g., water, chloroform), but the solute or solvent may be a gas, liquid, or solid. The solvent may either be a pure substance or a mixture. The term insoluble implies a solute is poorly soluble in a solvent. In very few cases is it true no solute dissolves. Generally, an insoluble solute still dissolves a little. While there is no hard-and-fast limit that defines a substance as insoluble, its common to apply a threshold where a solute is insoluble is less than 0.1 gram dissolves per 100 milliliters of solvent. Miscibility and Solubility If a substance is soluble at all proportions in a specific solvent, it is called miscible in it or possesses the property called miscibility. For example, ethanol and water are completely miscible with each other. On the other hand, oil and water do not mix or dissolve in each other. Oil and water are considered to be immiscible. Solubility in Action How a solute dissolves depends on the types of chemical bonds in the solute and solvent. For example, when ethanol dissolves in water, it maintains its molecular identity as ethanol, but new hydrogen bonds form between ethanol and water molecules. For this reason, mixing ethanol and water produces a solution with a smaller volume than you would get from adding together the starting volumes of ethanol and water. When sodium chloride (NaCl) or other ionic compound dissolves in water, the compound dissociates into its ions. The ions become solvated or surrounded by a layer of water molecules. Solubility involves dynamic equilibrium, involving opposing processes of precipitation and dissolution. Equilibrium is reached when these processes occur at a constant rate. Units of Solubility Solubility charts and tables list the solubility of various compounds, solvents, temperature, and other conditions. The IUPAC defines solubility in terms of a proportion of solute to solvent. Allowable units of concentration include molarity, molality, mass per volume, mole ratio, mole fraction, and so on. Factors That Affect Solubility Solubility may be influenced by the presence of other chemical species in a solution, the phases of the solute and solvent, temperature, pressure, solute particle size, and polarity.
