Independent trainer for the four NERC System Operator Certification exams: RC, BT, TO and BI. Scored against the cut score, never a percentage. 1,224 original questions, timed mock papers, a control-room simulator. Power Grid Operator Exam Prep covers the four System Operator Certification examinations of the North American Electric Reliability Corporation (NERC): Reliability Coordinator (RC); Balancing, Interchange and Transmission (BT); Transmission Operator (TO); and Balancing and Interchange (BI). One bank, four credentials All four examinations are drawn from the same six content domains and 31 knowledge areas; only the number of scored questions per area changes, and that table is published. Pick your credential and the app re-weights your readiness estimate, weak areas and mock papers. Scored the way the examination is NERC passes candidates on an absolute cut score, not a percentage: 92 of 120 for RC and BT, 76 of 100 for TO and BI. So the headline figure is a projected score out of the paper, and weak areas are ranked by how many scored questions they are costing you. Mock papers sampled to the outline A mock paper draws exactly the questions the content outline lists for each of the 31 knowledge areas, plus the 20 unscored trial items a real paper carries: 140 questions in three hours (120 on TO and BI). Flag and return; no feedback until you submit, then a full review. The control-room simulator Take a shift at the BA, TOP or RC desk in ten scenarios, from a unit trip at the evening peak and an IROL exceedance to EEA 3, a lost EMS, voice paths down and an evacuated control room. One model runs the system and the clock stops at each decision: read the live displays, choose what to do or answer a three-part communication, then watch it play out. The debrief counts, never as a percentage, the obligations you met or missed against the standards' own clocks, and explains every decision. Every number is tagged as a NERC figure, a value your company or RC sets, or a model assumption. New numbers every run. Home opens on a scenario for your credential: one tap starts a shift, and the debrief can drill the areas it exercised. Generated displays, new every time A six-bus one-line with flows, ratings and an N-1 contingency analysis report: find the worst contingency and decide what it obliges you to do. A Balancing Authority AGC control board, with the ACE left for you to calculate. Plus twenty drills. 1,224 original questions Written from freely published sources (content outlines, the NERC Glossary and the enforceable Reliability Standards). One free shift, then one payment Try it free: 50 practice questions in any mode, one full mock paper, one simulator run of any scenario, and every Library card. Full Access is a single in-app purchase that unlocks every question, unlimited mock papers on all four credentials, every trainer and all ten scenarios. One-time, no subscription, on your iPhone, iPad and Mac. The rest of the app 31 Library cards, each with seven must-know numbers and a short essay, plus an index of the 52 Reliability Standards the questions cite. Keyboard shortcuts on iPad and Mac. Spaced repetition brings back what you miss. Works offline and syncs through your own iCloud, with no account. Light and dark.
