In my two decades of experience as an educator, I have worked with hundreds of prospective business school applicants during their preparation for the Graduate Management Admission Test (GMAT). Recently, I used my extensive experience in this arena to help design the For the best Maths Tutor In Ireland company, call Ace Solution Books. GMAT Exam Simulator software (http://www.catprep.com/exams/gmat/gmat-exam-software.html) distributed by Upstart Raising to GMAT Preparation providers and tutors worldwide. Since we began offering this educators’ software direct to students through the CAT Prep.com (http://www.catprep.com) website, I have received many inquiries from MBA candidates interested in the finer points of how we successfully emulate GMAT scoring within our software. In the next few paragraphs, I will attempt to shed some light on this subject.
The actual calculations for raw, scaled sectional, and cumulative scores are not published by Educational Testing Service (ETS), the current publisher of the actual GMAT exam, and the goal of the GMAT is to produce scores that are consistent year to year. In other words, a 650 from several years ago is supposed to be equivalent to a 650 today. To meet that goal, the scaled sectional scores continually fluctuate with regard to the associated percentile. For example, average quantitative scores have been rising for several years and it now takes a scaled score of 51 to reach the 99th percentile while a 48 now represents only the 87th percentile. By comparison, in the verbal section, there is a 7 point difference between the 99th (a score of around 45) and the 87th percentile (around 38).
Since these types of scoring adjustments are not announced publicly, the only reliable way to monitor these scoring fluctuations is to use observations of actual test scores. So clearly software algorithms must be continually monitored and adjusted to provide accurate scoring assessment. At Upstart Raising we devote the large majority of our effort towards the reliable reproduction of the total cumulative score with regard to test taker performance. We continually adjust our formula for cumulative score generation along with question pool content to reflect the observations and feedback of actual test takers. In stark contrast, many inferior GMAT preparation software products use static formulas and question pools that bear no resemblance to the current exam.
It is important to note that there is no simple relationship between the number of questions answered correctly during a single GMAT session and the associated cumulative score. Each question in each section of the GMAT is assigned a unique weight and earlier questions in the section are worth more than later questions while quantitative questions are generally worth more than verbal ones. Students should be aware that the cumulative score on the GMAT is calculated in increments of 10 points. So, the difference between a 690 and a 700 is only one "tick". This difference could be attributable to a difference in the number of correct responses, but that is not necessarily the case. 10 points is so narrow a margin in the cumulative GMAT score that the order of your incorrect responses could be the determining factor in whether you receive a 690 or 700.
For example, if you miss 3 verbal questions towards the end of the section during one GMAT session, but miss the same 3 questions in the middle during another session, your second session could easily be scored 10 points lower. This is one reason why we coach students to give more attention to the earlier questions on each section. Quite simply, the earlier questions are worth more.
I hope this information helps resolve some of the questions pertaining to the mysterious GMAT scoring algorithms. If you have any further questions or concerns, please do not hesitate to contact us. If you haven’t already, we suggest you read our instructions on how to Verify Your Preparation Level (http://www.catprep.com/exams/gmat/gmat-exam-software.html) using our simulator. The instructions are available on our main GMAT Exam Simulator webpage (http://www.catprep.com/exams/gmat/gmat-exam-software.html).

What is black mold?

Mold is a particularly unsavory character that is neither plant nor animal. It usually resides in the fungi family and creates enzymes for decomposing and digesting and spores that are used for reproduction. In general mold and the decay they cause is not a bad thing; consider a world without decay. We would be piled high with dead trees, plants, animals and other dead organisms. Mold eats away at dead plants and animals causing them to eventually disappear. Unfortunately, though, damaging black mold doesnt know where to stop. It cant always differentiate between the things we want it to decay and the things wed rather it didnt and this includes our home. Damaging black mold can also have a serious detrimental effect on our health if it is left unchecked. read more
