NERC System Operator Certification · RC · BITO · TO · BI
Closed-book exam. Current-standards prep.
The SOC exam is closed book, and NERC revises its standards constantly. Every question here is verified against the standard version currently on your exam, then pulled for re-verification the moment that version changes. Drill the Glossary, sim the real exam’s shape, and see where you honestly stand.
Free to start. No card required.

Recall · Resource and Demand Balancing
Under the current standard, the Contingency Reserve Restoration Period gives a Balancing Authority how long to restore its Contingency Reserve?
Readiness · Reliability Coordinator
Pass mark ~76.7%, a recent Reliability Coordinator cut score (NERC sets each form’s exact passing score). We show you where you honestly stand against it.
The currency promise
Standards change. Your prep shouldn’t quietly go stale.
Every question is verified by a subject-matter expert against a specific NERC document version and stamped with it. When NERC activates a new version of a standard, every question citing that document is pulled from delivery and individually re-verified before it can serve again. That includes the Glossary.
We publish the audit trail: which document versions the bank is verified against, when they were activated, and when the last revision sweep ran.
Built for a closed-book exam
Glossary drills
Flashcard-style drills over the NERC Glossary of Terms. See the term, recall it cold, then reveal and answer for real. The exam leans hard on exact definitions, and closed book means recall, not lookup.
Realism toggle
The real exam seeds unscored experimental questions you can't identify. Flip the toggle and your sim does the same (unmarked, excluded from your grade), so exam day feels like practice, not the other way around.
Honest readiness
A readiness estimate computed from your practice against your exam's published outline weights, per knowledge area, updated as you work. It's an estimate, never a pass guarantee. No honest tool can promise you a result.
Pricing
The exam costs about $700 to sit and $700 again to retake, and roughly 40% of first-time candidates fail. We keep one verified question bank, authored to the RC superset outline. Buy the exam you’re sitting and you get that exam’s slice at its outline weights, or grab the cram pass for all four. It’s a one-time purchase, a fraction of a single retake.

Questions
Is this a subscription? How do I cancel?
It isn't a subscription, so there's nothing to cancel. Every plan is a single payment that unlocks access for a fixed window — 30 days for the Cram Pass, 12 months for the per-exam plans. We don't keep your card on file and you're never charged again; when the window ends your account returns to the free plan.
Is the exam really closed book?
Yes. You get no standards, no notes, and no Glossary at the terminal. So the prep here trains recall and application, not lookup. Sims hide citations until you submit, same as the real thing, and the full citation review comes after.
What documents are your questions based on?
The NERC Reliability Standards families on your exam's published content outline (BAL, EOP, TOP, and the rest) plus the NERC Glossary of Terms. Every question cites the exact document and version it was verified against.
How current is the question bank?
We watch NERC's standards activity as a documented process. When a new version becomes active for the exam, every question citing that document is pulled from delivery and re-verified by a subject-matter expert before it can serve again. The public currency ledger shows the versions and the last sweep.
Do you guarantee I'll pass?
No, and we're proud of that. No honest tool can. What we can do is give you a straight readiness estimate against your exam's outline weights and target your weak spots, so you walk in prepared.
Which exam should I buy?
The one you're sitting. It's one verified bank authored to the RC superset outline, and each purchase unlocks that exam's mapped slice. If you're not sure yet, start free. The sample tier keys on RC until you pick.
