Get help with CertVector

CertVector is a certification prep platform built around practice questions, missed-question review, timed simulations, readiness tracking, and personalized tutor explanations. The goal is to show what to study next instead of making learners guess.

No. Security+, Network+, CCNA, AWS Cloud Practitioner, AWS Solutions Architect Associate, Azure Fundamentals, Azure Administrator, CompTIA A+, and PMP are live course tracks using the same practice, review, simulation, and course-based Pro access system.

The current live tracks are CompTIA Security+, CompTIA Network+, Cisco CCNA, AWS Cloud Practitioner, AWS Solutions Architect Associate, Microsoft Azure Fundamentals, Microsoft Azure Administrator AZ-104, CompTIA A+, and PMP.

No. CertVector uses original training questions and scenarios. The questions are written to teach exam objectives and practical reasoning, not to copy or expose real certification exam content.

No. CertVector is an independent study platform. Certification names and trademarks belong to their respective owners and are used only to identify the exam track being studied.

Practice can be mixed, focused by domain, filtered by difficulty, or driven by missed and saved questions. Pro users get broader access to the active question bank for the course they upgraded.

Practice is for learning with explanations after each answer. Simulation is a timed checkpoint that behaves more like an exam readiness test and updates readiness history after completion.

Missed-question review turns wrong answers into a study queue. It helps learners revisit weak concepts until the explanation and reasoning become familiar instead of only seeing brand-new questions.

Yes. When you sign in, CertVector saves answer history, weak domains, saved questions, review queues, course interest, and plan status to your account so you can return later.

Practice depends on saved progress, daily usage limits, review queues, course entitlements, and anti-abuse controls. Public visitors can browse course pages first, then sign in when they are ready to practice.

Yes. The public sample library shows original sample questions for every live track. These samples are separate from the paid practice bank and do not count against daily practice limits.

Yes. The free plan lets you try the study workflow with daily practice limits, limited tutor usage, and starter access. It is meant for evaluation and light daily practice.

Pro unlocks higher usage limits, broader active question bank access, timed simulations, deeper scenario coverage, allocated AI tutor usage, and stronger review workflows for the specific course you purchase.

Pro is course-based. If you upgrade Security+ Pro, that gives Pro access for Security+. Future exam tracks can have their own pricing and access. CertVector can support an All Access option later if it becomes useful.

Yes. Each course can have its own monthly or annual price depending on content depth, question bank size, simulations, and ongoing maintenance.

Use the exam catalog or pricing page and select the course you want. Pricing is course-specific, so the checkout and Pro entitlement are tied to the selected certification track.

CertVector uses objective-mapped answer evidence such as correctness, confidence, response time, difficulty, prior attempts, course coverage, assessment results, and recency. One answer can move a signal, but repeated and varied evidence makes it more reliable.

Confidence helps distinguish a certain answer from an uncertain answer or guess. A high-confidence wrong answer can indicate a confidence mismatch or misconception, while a low-confidence correct answer may need another retrieval attempt before it represents durable mastery.

Readiness estimates current preparation using mastery, assessments, consistency, retention, trend, and coverage. Model confidence describes how much evidence supports that estimate. High readiness with low model confidence should be treated cautiously until more objectives and timed assessments are covered.

No. Pass probability and estimated exam score are directional model outputs based on CertVector activity. They are not official vendor predictions and cannot account for every exam form, study activity outside CertVector, or exam-day performance.

Correct knowledge can weaken when it has not been retrieved recently. The forgetting estimate helps schedule another review before the platform treats old evidence as equally strong forever.

Mission priority considers low mastery, estimated forgetting, mistake frequency, overdue review timing, and prerequisite impact. It then selects a small number of Learn, Practice, or Review actions that fit the available study time.

Root-cause analysis looks for study patterns behind incorrect answers, including knowledge gaps, weak prerequisites, confidence mismatches, repeated misconceptions, and unusually fast careless mistakes. These are probabilistic learning signals, not definitive judgments.

The tutor explains the concept behind a question, why a selected answer was wrong or right, and how the issue connects to the learner's weak domains and recent mistakes. It is constrained by the validated question context, explanation, objective mapping, and available reference guidance.

It uses the current question context, selected answer, explanation, and available learning signals such as weak domains and missed-question patterns. That helps the response stay focused on the learner's actual gaps.

No. The tutor is a study aid. Passing depends on preparation, exam readiness, practical understanding, and performance on exam day.

AI tutoring has real operating cost and abuse risk. Free learners have a question-count limit, while Pro learners see allocated AI tutor usage. Limits keep the platform reliable, control spending, and help keep pricing realistic for learners.

Report it from the question workflow or contact support. Tutor reports are reviewed alongside question-quality reports so unclear wording, weak explanations, and incorrect coaching can be investigated.

The sample library contains a small set of original questions for each live track, with answers and explanations. It helps prospective learners judge the question style before creating an account or upgrading.

No. Samples are public preview items. The full practice bank remains inside the signed-in practice, review, and simulation workflows.

Resources contains short articles about study strategy, exam planning, question quality, and product usage. It is separate from the question bank and includes an RSS feed for new posts.

No. CertVector resources help explain study decisions and practice strategy, but learners should still review official exam pages and objectives from each certification vendor.

CertVector uses email-code sign-in. Enter your email, receive a short login code, and verify it. You do not need to create or remember a password.

Billing is processed securely through Stripe. CertVector does not store full payment card details in the application database.

Yes. Billing management is handled through the customer portal. After cancellation, your Pro access follows the subscription status and billing period rules shown at checkout.

Use the report option on a question or contact support. Reports help identify unclear wording, weak explanations, objective mapping issues, and possible duplicates.

Contact billing@certvector.com with the account email you used at checkout. Admins can review subscription status, webhook history, and course entitlements to fix mismatches.
