Database Statistics: Here's how our databases compare to published statistics: The US Bureau of Labor Statistics classifies 840 job categories. Our database is slightly more refined, and includes over 918 categories with over 1,000 fields. Of these categories, about 80% require a test or exam of some kind, and each of the 50 US States and over 200 countries have their own slightly varying different versions of these exams in many categories. Some professions are standardized, others vary by area. We have over 200,000 specific exams on file representing an average of 100 questions for vocations and professions, including all States and associations. CLICK HERE to SELL US your exam, test prep materials, texts, or to get paid for your exit interview!
Academia and academic studies are listed in 1,528 subject categories, with nearly 3,000 individual detailed subjects, by the Department of Education, Wikipedia's list of subjects, and a variety of national education councils and associations. Our databases generally correspond to this number, with tests and exams in 1,936 academic topic areas not including vocational keywords. Our current, comprehensive test banks contain more than a million entries (questions), with over 4.8 million in process at any given time! The disparity is that many of the questions do not "make it" into widely accepted venues for the most necessary exams, but every well posed question has learning value, many much more so than lengthy discussions or equations, because solving problems and completing exercises gives a "real world" feel for the subject matter, especially when augmented with animation, illustration and video explanations of both right and trick answers. Our exclusive EDUTOKEN network PAYS students for right answers when gaming for test prep on their computers, smart phones or other devices. PREPTORIAL'S DATABASES AND LIBRARIES ARE SO LARGE THAT THEY ALL RUN BENEATH YOUR DEVICES ON THE BIGHAL HYPERCOMPUTER.
Databases Organization: Our keyword searches identify questions with lightning fast, complex, thorough, bayesian, robust data mining algorithms that are proprietary and specialized to your search. For example, our searches cross reference over 1,000 job, vocation and profession categories; nearly 3,000 academic subjects; over 5,000 professional associations, companies, societies and bodies of knowledge that conduct, score or create testing; over 33,000 test banks/cd's/publications (Bing and Google have over 100 million keyword results for test prep and test bank links), and the world's largest database of current, complete questions, answers and explanations, many animated or video, all with robust illustration. WHY PAY THOUSANDS FOR YOUR PREP WHEN YOU CAN GET THE MOST CURRENT, COMPLETE BANKS FREE?!
Example: You can get a PhD in Actuarial Science, a Masters in Programming, or have 20 years of experience as a Locksmith, but if you can't pass the Actuarial Society Exams, Microsoft Certification, or the ASLPA Exam, you won't get a job, and you won't be licensed! Same with ACT, SAT, GRE, GMAT, LSAT, MCAT and hundreds of others for academic admission and achievement.

Physical Texts Note: Preptorial now has access to over 9 million + titles, over a million journals, and over 20,000 software programs, the highest in the world for ANY test prep service, thanks to the generous help of libraries, Amazon, Barnes and Noble, Google, Questia, DOAJ, hundreds of publishers including university publications, Microsoft, Scribd, and the top 500 AM sellers, who inventory a million books or more. For comparison, Amazon generally has over 12 million titles any given time, not including ebooks. In support of our mission, we are ensuring that every title is available electronically, including those classic or long out of date and public domain. Email us if you have books you'd like to donate, in any condition or format. The only requirement is that they must contain problems and solutions or questions and answers (ie: no novels, biographies, etc.), with an emphasis on technology, including vocational as well as scientific technology. ALL DATABASES AND PREP SETS, INCLUDING PRINT, ARE CURRENTLY BEING DIGITIZED FOR INCLUSION AND PROCESSING ON THE BIGHAL HYPERCOMPUTING PLATFORM.
What is ProblemEngine™? (A Preptorial PROJECT, driven by ANSWERLOCKER.com on our proprietary BIG HAL hypercomputing systems).
Databases are only as good as their underlying indexing technologies. At the user level, these are seen as keywords, topics, subjects, and high level categories. In the back room, the coding is about giving you the most relevant set (question/ answer, problem/solution, exercise sets) for your needs.
Needs vary, and so does ProblemEngine. Are you taking the SAT? Are you teaching string theory? Are you qualifying for Microsoft O/S, Cisco Network, Oracle database or IEEE circuit design certification? Do you need to pass the State of Delaware Polygraph Examiner certification exam? Do you need Mrs. Altmann's 2018 Geometry exam? Are you interviewing with Google for a Data Scientist position? Millions of these types of objectives and their needs are included in every type of search, from raw keyword, to questions and needs in the exact form above.
All these benefits and tools are rolled up into the most innovative, FREE elearning software system in the world: ELWIN, our GNUCAD program that integrates questions, answers, problems, solutions, hints, tips, clues, formulas, etc., all in a single, user-friendly drag and drop interface.
Many web services like Wolfram, Wiki, Google, Bing and others are working on "user friendly" question formats, but it is easier for us, because of our laser focus on prep and q/a, p/s, exercise pairs. Most of the advanced forms of these only result in vaguely related forums on today's searches, but with specialized databases, the "top 10" results can be direct answers to your exact questions.
This also is the future of Wikipedias, and the present of our own captive "relational" Wikis: How does A relate to B?"What is the difference between a remainder and a modulo?" Just like Jeopardy, if you ask this on ProblemEngine, you'll get a question/answer, problem/solution, exercise response, and you can specify if you want a single answer set, a complete exam, at what level of difficulty, and in what format: written, audio, video, hinted, animated, illustrated, broadcast, or an entire cited bib, index, glossary and text.
AND: how FUN do you want it? Fast and dry? As a puzzle? Game? Smart phone or email text, app or answer? Graphic novel? Who says test or interview prep can't be fun? We're even working on VIRTUAL JOB INTERVIEWS with real interviewers using 3D RIFT technology.

Thought for the day: THE INTERNET IN 1936?
“A mechanism of world inter-communication will be devised, embracing the whole planet, freed from national hindrances and restrictions, and functioning with marvellous swiftness and perfect regularity.”
--Shoghi Effendi, The World Order of Bahá’u’lláh, op. cit., p. 203, March 11, 1936
What is Amazon Bib? Our hundreds of millions of test prep/ Answer bank pairs are ALL CITED via TEXTBOOKS, journal articles, references, bibliographies, etc. to maintain quality, accuracy, sourcing and accountability. We have compiled these millions of references via BIG HAL with our BibFeed project, and now EACH of those references and citations, with the help of our Texts in Print subsidiary and Amazon ranks and reviews, is now being LINKED to Amazon so that every citation has a related, current text, sorted by quality of Amazon review, availability, new editions where available, level (Child, Youth, Adult Ed/college, Grad/Postgrad) as well as SUBJECT (career, course, science, etc.). WE ARE CURRENTLY CROSS REFERENCING these texts, bibs and citations with CLASS numbers across the US and world so that each text linked has best seller, frequency of use, currency and review rankings.
