The CodeHS Cybersecurity Level 1 (CHS-CY1) exam has 45 questions and is completed in 1 hours 30 minutes. Our timed practice tests mirror that length and pacing, so exam day feels familiar.
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the CHS-CY1 exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
No. CHS-CY1 Exam Prep is an independent study resource for CodeHS Cybersecurity Level 1 (CHS-CY1). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.
Every paid plan unlocks the full bank of 1,000+ practice questions covering all 6 CHS-CY1 domains - Cybersecurity Essentials: Ransomware; Phishing; Internet of Things; The CIA Triad; Cyber Ethics; Credit and Copyright; Legal vs. Ilegal Hacking, Cryptography: Basic Cryptography; Code Breaking; Brute Force; Frequency Analysis; Caesar Cipher; Vigenere Cipher, System Administration: Operating Systems; Software & Software Licenses; Application Security; Browsers; System Administration; Command Line System, IT Concepts: Internet Addresses; IPv4 and IPv6; DNS Hierarchy; Routing; Packets and Protocols, IT Infrastructure: Internal Components; Peripheral Devices; Network Devices; Storage Options; Network Options; Network Communication; Network Management, and Digital Safety and Data Security: Digital Footprint; Cyberbullying; Internet Safety; Clients and Servers; SQL Queries; SQL Injection; Developer Tools. You can practice the whole bank, filter by domain, or run a timed, domain-balanced exam simulation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Chat with us any time - the 24/7 support chat in the corner of every page gives instant answers about plans, access, and billing. Prefer email? The contact link is in the footer. Payments are processed securely by Stripe, and active customers can download an invoice from their profile page.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email us from the contact link in the footer and it'll be sorted out.

Real feedback from CHS-CY1 candidates on Reddit.
"put this off for like two weeks then crammed the practice sets the night before. the caesar cipher and vigenere questions on the real thing were basically the same style. passed, barely studied otherwise lol"
"honestly wasnt sure a prep site could help with something this broad but the mistake review after each quiz actually showed me i kept mixing up ipv4 vs ipv6 stuff. fixed that and the real exam had like 4 questions on it. used chscy1exam.com for about a week, got a 78"
"took this as part of a class requirement so i wasnt super motivated at first. what actually got me there was just grinding the full length mock exams on this site, timing myself so the 90 minutes didnt feel so long. the sql injection questions were the ones i definately needed the extra reps on."
