TradePrep now covers seven licensing and certification exams across five trades, not just general contracting. Same app, same account, and one subscription still covers all of them. NEW EXAMS • EPA Section 608 — Core, Type I, Type II and Type III • Journeyman Electrician — NEC-based • Journeyman Plumber — IPC-based • ICC B1 Residential Building Inspector — IRC-based Every exam ships with a full practice bank, two complete timed mock papers, and a written explanation on every question — including why each wrong answer is wrong. BUILT FOR OPEN-BOOK EXAMS The electrical, plumbing and inspector exams let you bring the code book. Practice questions cite the section, and a tab-kit tells you which pages to flag before test day. Closed-book exams get study notes instead. CALCULATION DRILLS Pick one skill and work it: load calculations, ampacity and voltage drop, fixture units and pipe sizing, spans, footings, egress dimensions. FASTER START Setup is six steps and drops you straight into studying. ### 1.1.4 — 2026-07-14 What's New ： Small update, smoother experience. • Never study on a stale version again — ContractorPass now lets you know right in the app when an update is out, one tap to grab it. • Under-the-hood improvements so we can find and fix rough spots faster. • Minor fixes and performance polish throughout. ### 1.1.3 — 2026-07-08 What's New： Sharper explanations and a smoother study flow. • Explanations, redesigned: why it's right, why the others are wrong, where to find it in the books, what it tests — plus an exam tip and a memory hook, in one clean layout. • Answer a question and the page glides straight down to the explanation. • Mistakes: tap any missed question to re-do just that one. • "Open in Reference" now jumps to the exact book — no more hunting the shelf. • Mock exams: Submit now works even with unanswered questions, and the book-finder button sits in the right corner where your thumb is. • Assorted fixes: exam switcher responds on every tab, sheets size to their content, and more. ### 1.1.2 — 2026-07-01 ContractorPass now prepares you for three exams — not just one. • Three exams, one app: NASCLA (valid across 16+ states), Florida, and California. Switch anytime — one subscription covers all three. • New Reference tab: For open-book exams (NASCLA, Florida), the book-finder tells you which reference book — and exactly where — so there's no page-hunting on exam day. For California's closed-book exams, study the source material distilled into rules, key numbers, and common traps. • New Mistakes tab: Every question you miss is saved automatically. Re-do them until they stick — cleared when you get it right, back if you slip. • Rebuilt Practice: Track mastery area by area with question-by-question progress, plus focused Calculation and Plan-reading drills. • Full mock exams: Sit a complete, timed paper under real exam conditions, with a by-area breakdown of where you stand. • A cleaner, faster, fully redesigned experience throughout. Already a Pro subscriber? Your access carries over automatically — nothing to do. ### 1.1.1 — 2026-06-08 What's New in This Version A major refresh focused on getting you to a personalized plan, faster. • New onboarding flow: in about 3 minutes we map your state, exam date, weak spots, and study window into a custom plan tuned to how you'll actually be tested. • Smarter diagnostic: each question now comes with a full breakdown — why the right answer is right, why each wrong answer is a trap, and an exam tip to help it stick. • Redesigned subscription page: shows your personal plan summary, a side-by-side comparison of Free vs Pro features, and our Pass Guarantee — full refund if you don't pass. • Daily reminders: lock in a study time during setup so you don't lose your streak. • 40+ new construction-themed illustrations throughout the app. • Renamed to "Contractor Prep" on your home screen for clarity. Good luck on your exam — and thanks for letting us help you get there ## Apps similar to TradePrep | App | Rating | Price | Category | | --- | --- | --- | --- | | [NASCLA Contractor Exam Prep](https://appshunter.io/ios/app/nascla-contractor-exam-prep/id6749447151) | 5.0 (1) | Free | Education | | [General Contractor Exam 2026](https://appshunter.io/ios/app/general-contractor-exam-2026/id6547831931) | 4.4 (14) | Free | Education | | [Electrician License Exam 2026](https://appshunter.io/ios/app/electrician-license-exam-2026/id6746489371) | — | Free | Education | | [NASCLA Test Prep](https://appshunter.io/ios/app/nascla-test-prep/id6752681081) | — | Free | Education | | [DMV Permit Practice Test 26](https://appshunter.io/ios/app/dmv-permit-practice-test-26/id6761602648) | — | Free | Education | | [Contractor License Prep](https://appshunter.io/ios/app/contractor-license-prep/id6763968210) | — | Free | Education | ## More apps by Shanghai Xushu Information Technology Co., Ltd. - [Logo设计软件 - Logo创意商标制作](https://appshunter.io/ios/app/logo-logo/id6478654269) - [宅地建物取引士一問一答• 模試对策](https://appshunter.io/ios/app/id6757780918) - [EstatePass: Real Estate Exam](https://appshunter.io/ios/app/estatepass-real-estate-exam/id6758002727) - [기출문제 - 공인중개사 시험 기출](https://appshunter.io/ios/app/id6760986723) - [공인중개사 모의고사 - 실전 시뮬레이션](https://appshunter.io/ios/app/id6760994332) - [NMLS Prep - Mortgage Exam 2026](https://appshunter.io/ios/app/nmls-prep-mortgage-exam-2026/id6761251885) All apps by Shanghai Xushu Information Technology Co., Ltd.: https://appshunter.io/developer/1733615663 ## Related topics [1099 contractor](https://appshunter.io/ios/topics/1099-contractor) · [nascla contractor exam prep](https://appshunter.io/ios/topics/nascla-contractor-exam-prep) · [contractors license exam prep](https://appshunter.io/ios/topics/contractors-license-exam-prep) · [general contractor exam prep](https://appshunter.io/ios/topics/general-contractor-exam-prep) · [contractor license prep](https://appshunter.io/ios/topics/contractor-license-prep) · [contractor exam](https://appshunter.io/ios/topics/contractor-exam) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
