About and methodology

How we build Alarm Ladder, check our material and handle corrections.

Who we are

Alarm Ladder is part of TrueGrade Prep. We make study resources for NICET FA I, NICET FA II, NICET I&T FA, NICET FA III, NICET I&T FA I, NICET FA IV candidates.

Operating company: Nori Software LLC.

What we build

We build free practice checks, calculators and guides to help you find gaps in your knowledge and plan your study time. Each exam also has a full course: lessons for every task in the published outline, a question bank, timed practice exams and a study plan.

How we write and check questions

Questions are drafted with AI assistance from NICET's content outline, then each answer key is re-checked by a separate blind solve and against the code section or source it cites. Questions an expert reviewer has signed say so; every question, signed or not, is corrected as errors are reported.

We write each question from scratch. Each question is mapped to a domain and its published weight, so free check question selection follows the outline's balance. Code references cite section numbers only; we never reproduce code-book text. Use your own licensed copy of any code your exam requires. We never use real or recalled exam items, and reject questions that resemble them.

A question is removed from use if its answer is unreliable, its wording is ambiguous or its reference is out of date. Questions that cannot be corrected are retired, and corrections are recorded in the errata log.

How we check facts

Facts about fees, exam formats and rules link to the exam body's own pages and show the date checked. Those pages are the source to consult before booking or applying. Reported errors go through the corrections process below.

Who checks our questions

Outside experts sign off on question sets. We describe each reviewer by their background and do not publish names unless a reviewer has agreed to it. A reviewer is credited only on the questions they signed.

Our method

  • Original questions, written to NICET's published outline. Never real or recalled exam items.
  • Every answer key is confirmed by a separate blind solve.
  • Explanations cite the clause, table or figure they rest on, never code-book text.
  • Reported errors are corrected within 2 business days and logged in the public errata log.
