The numbers on this test are real numbers. You may assume that positions of points, lines, and angles are in the order shown. A figure accompanying a problem-solving question is intended to provide information useful in solving the problem. Figures are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. Straight lines may sometimes appear jagged. All figures lie in a plane unless otherwise indicated.

®

® In data-sufficiency problems that ask for the value of a quantity, the data given in the statements is sufficient only when it is possible to determine exactly one numerical value for the quantity.

®

Example 1

What is the value of x + y?
(1) 0.5 (x + y) = −1 1 1 (2) x + y = 2 5 5

A

B

C

D •

E

From (1): x + y = −2, so (1) is sufficient. From (2): x + y = 10, so (2) is sufficient.
Example 2

DIRECTIONS: Data-sufficiency problems consist of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements is sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient. E. Statements (1) and (2) TOGETHER are NOT sufficient. ® A figure accompanying a data-sufficiency problem will conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).

N is a number in the set {35, 38, 41, 44, 47, 50}. What is N? A B C D E
(1) N is a multiple of 5. (2) N is even.


From (1): N = 35 or 50, so (1) is not sufficient. From (2): N = 38, 44, or 50, so (2) is not sufficient. Taking (1) and (2) together, N = 50, so taken together (1) and (2) are sufficient.
1. A club wants to mix 20 pounds of candy worth $8.00 per pound with candy worth $5.00 per pound to reduce the cost of the mixture to $6.00 per pound. How many pounds of the $5.00 per pound candy should be used? A. B. C. D. E. 20 30 40 50 60

Ethics

...THE SITUATION Georgia’s hands were sweating. She was fifteen minutes into her math final when she began to panic. This exam was worth most of her grade in the class. She understood math—even liked it—and usually did really well. Her constant problem was that she wasn’t a strong test-taker. Her grades never reflected her understanding of the material she studied. Now, here she was, once again stuck on one problem worth twenty-five points on the test, and she was drawing a blank. She put her head down on the desk and concentrated as hard as she could. She remembered doing a similar problem in class and explaining it to her friend Jessie, but now she was so stressed out by the test, she couldn’t even remember how to begin the problem. She lifted her head and stared at her test. She listened to the clock tick on the wall and imagined her parents’ expression when she receives her report card. Jessie was sitting right in front of her. He is always a good test taker and had already solved the problem. The teacher had his backed turned and was on the other side of the room. Georgia could look over Jessie’s shoulder, get the answer, and no one would know. Georgia needed to think quickly. She thought about how unfair it was that she regularly does badly on tests even though she works so hard in class and understands the material, too. She thought about how often she helped Jessie in class throughout the semester. What should she do? She prided herself...

Advantages and Disadvantages of Formal and Informal Assessment

...assessments have their advantages and disadvantages. Formal assessments are standardized tests that are designed by test specialists. There are given and scored under a standard condition. Informal assessments are tests designed by teachers for use in their classroom. Standardized tests are a type of formal assessments. Standardized tests are formal assessments because the tests are given in the same manner every time. They are fixed choice tests. It is a published achievement test. These are assessments that have been made to allow students to answer a vast amount of questions in a short time period. Since these tests are standardized they will all be the same unless there are different versions of the same test with the questions in different order. By using the same tests the answers can be machine scored. There will not be any mistakes due to grading error. They are convenient to assess student’s knowledge. These are the advantages of using standardized tests. With any given test there are some disadvantages to them, even those designed to be the best. Since standardized tests are fixed choices tests, they can exaggerate accurate information and minimal level skills at the sacrifice of advanced order problem solving and conceptual skills. They also take away from teaching time. These tests usually last a few hours, and during this time students are not learning. Standardized tests also do not assess the same curriculum. Every state has its own curriculum that it...

...Part 2 – Analysis of an Argument [pic] The author criticizes video games being a negative impact on youth in the initial analysis and later he provides an evidence saying over 25 years, actually youth of the nation is doing well in the college aptitude tests and the entry level salaries are increased for college graduates, where the video games were used more. This shows the weaken argument and evidences, as the good maths score and increase in entry level salary could be dependent on many factors like economy doing well in these years and increase in the number of colleges and those aptitude tests. In the author’s first assumption, over these 25 years, the math scores of the students have raised in the commonly used college test, there could be few other factors influencing this like students preparation for test, competition among other students, due to increase in college numbers over that period tests would be relatively similar. There is no evidence from author on the stats of students who play video games and who score well in aptitude. Video games could have been recreation act for the students, but not all the students or youth necessarily would play video games. Also there is no mention of the amount of time they play the games. In the second assumption, author provides another evidence saying entry level salary increase for the college students, there could as well several reason for this like student’s academic performance, economy doing well, job...

Test Taking

...you feel about tests in general? I don’t like taking test because I always get of feeling of nervousness. My stomach gets all tied up in knots. The problem with taking test is a feeling of not remembering. It gets uncomfortable every time I have to take a test whether I study or not. 2. What are your first memories of being in a testing situation? What were your feeling, and why? My first memory of being in a testing situation is in high school. It was finals and I needed to pass this one course to graduate. It was a course that I detested, and I was horrible at it. This course was Trigonometry. I am not good in math period, but this course was a requirement. I felt that I was going to fail the course, and it was going to be a setback. It was a depressing feeling. 3. What make a test “good” and “bad” from your perspective? What make a test good is knowing what kind of test it, what is covered and how much a percentage is geared toward that test. How do I know that the test is good is when the instructor lets you know what is going to be on the test. A test is good when much preparation and work goes into it. The format or the structure of the test also make it good. When I think of a bad test, it mean no preparation, no work or study when into taking the test. A bad test is a test that is not put together well. The organization is not good and the test is very confusing. It can be a bad test when the person taking the test is ill-prepared...

Standardized Test, Assessments, and Portfolios for Reading

...Running head: Standardized test, assessments, and portfolios for reading Standardized test, assessments, and portfolios for reading Students are constantly being “assessed” by their teachers. We examine their behavior patterns, learning styles, reading abilities, and even their happiness. The purpose of assessments is to educate the teacher on what our students know and how we can better serve them in learning the curriculum and more. State tests are administered yearly for students, and teachers give formative and summative assessments frequently in the classroom. There are benefits and downfalls to each type of assessment. Afflerbach (2005) discusses that the results from standardized reading assessments are “at best an approximation of the students’ actual achievement level” (p.158). Standardized test tell us if our student is above, at, or below proficient. They do not tell us what areas the student does well at or what skills they are lacking in. According to the work of Buly and Valencia (2002), “Students scoring below proficient on state assessments are usually placed in supplemental or remedial reading classes, which often focus on phonemic awareness and decoding skills at any grade level (Buly & Valencia, 2002). After being put in these “special help” reading classes, the student then goes back into content area classes (English, Math, Science) which all have difficult text where the student struggles with comprehension. The problem we are then...

Assessment of Learning

...Alternative Assessment An assessment in which students create an original response to answer a certain question. Students respond to a question using their own ideas, in their own words. Examples of alternative assessment are short-answer questions, essays, oral presentations, demonstrations, performance assessment, and portfolios. Other activities included in this type are teacher observation and student self-assessment. * Components of Alternative Assessment a) Assessment is based on authentic task that demonstrate students’ ability to accomplish communication goals. b) The teacher and students focus on communication, not on right and wrong answers. c) Students help the teacher to set the criteria for successful completion of communication tasks. d) Students have opportunities to assess themselves and their peers. Performance-based Assessment Performance assessment ( Mueller, 2010) is an assessment in which students are asked to perform real world tasks that demonstrate meaningful application of essential knowledge and skills. It is a direct measure of student performance because the tasks are designed to incorporate context, problems and solution strategies that students would use in real life. It focus on processes abd rationales. There is no single correct answer; instead students are led to craft polished, thorough and justifiable responses, performances and products.

Should We Get Rid Of Electives In Schools

Many schools are wanting to get rid of electives as a way to meet the increase in passing the tests at the end of the year. They want the students to focus more on the classes and the test preparation courses for those tests. They think that getting rid of the music and arts electives will help this. They are actually wrong with this mindset. Students in the music and art classes actually learn better than those who are not. They also score better scores due to their better ability to learn. Therefore, they are not really helping the children do better on these tests....
