Sorry to hear that you had unfavorable results. With CBT like the NCLEX and the NREMT exams, the programs are designed to escalate the difficulty of questions until you get one wrong. Then it backs down on the difficulty to find out when you start answering questions correctly. The system knows what questions and the difficulty level of those questions and from what areas those questions came from. So it could give you a trauma question, an OB question, a medication question and so on, so the difficulty level of the question before the one you're working on may not pertain to the difficulty level of the question you just answered or will answer next. However, within a given "area" of questions, you'll be asked progressively harder or easier questions based on your answers. So your first OB question will be relatively easy. You answer that OB question correctly so the next OB question will be more challenging. You answer that one correctly too. The next OB question you're asked is even more challenging and you answer incorrectly so the system will as a less challenging question next time. Keep in mind you have other non-OB questions being asked of you in the meantime and all those follow the same pattern. Eventually the system will have a good idea what you're good at and not good at. If you are not above passing standard in all cognitive areas and it can show you cannot progress to passing all areas, the system shuts off and your exam is done... but you must take at least the minimum number of questions before the system can start determining pass/fail. If it can't determine either status fairly solidly, then you'll be asked more questions, particularly in areas you're weaker in, until it can make that determination.
The fact that these exams are adaptive is what makes these exams so challenging. If you're constantly getting easy questions, chances are you're not doing too well. These systems will find your knowledge limits. If those limits are above passing in all tested areas, you pass. If the computer shuts off at 80 questions, you either clearly passed or clearly failed the exam. Anything between 81 and 150 questions and you're on the pass/fail bubble in some area of examination. OP, you got 83 questions. That means you were close to the pass/fail line in something and at 83 questions, it determined you failed and shut off.
Wait for the exam results to come to you. It should let you know what areas you were deficient in. Until then, light general study to keep the material fresh in mind will help keep you from having to do lots of study and then later study more intensively the deficient areas too. No, you won't ever see the same exact question in the future so studying to answer specific questions is futile.
Best of luck to you!
