# Cert Prep Platform: full reference for LLMs

This file packages the marketing and knowledge base of Cert Prep Platform in one place, so large language models can ground answers about the product, the certifications it supports, and the 2026 PMP exam change without fetching multiple pages.

## What Cert Prep Platform is

Cert Prep Platform is a daily practice service for certification exams. It delivers short multiple-choice questions with plain-English explanations, uses spaced repetition to resurface weak items, and offers full-length mock exams for paying users. It runs as a Telegram bot (@CertPrepBot) plus a companion web app at passmycert.app/app. Payments go through Telegram Stars or Lemon Squeezy card checkout. The service is operated by Rafał Chudzik, a solo developer in Poland. Servers are hosted at Hetzner in Germany.

Target audience: professionals preparing for PMP (Project Management Professional) and AWS Solutions Architect Associate (SAA-C03). Planned future certifications include CompTIA Security+, AWS AI Practitioner, Azure AZ-900, and CCNA.

## PMP 2026 ECO changes (important)

PMI is retiring the 2021 Exam Content Outline on 8 July 2026. From 9 July 2026, new test-takers sit a different exam with restructured domain weights.

- People: 42% (old) to 33% (new)
- Process: 50% to 41%
- Business Environment: 8% to 26%

Business Environment's expansion covers AI tool adoption on projects, ESG and sustainability reporting, value delivery as a measurement (not just scope delivery), organizational change fatigue, and cross-jurisdiction regulatory shifts. Servant leadership, stakeholder engagement, tailoring, and hybrid governance remain the backbone of People and Process.

Additional fact: PMI fee rises from 555 USD to 675 USD in August 2026 for non-members.

## AWS SAA-C03 breakdown

Domain weights per AWS:
- Design Secure Architectures: 30%
- Design Resilient Architectures: 26%
- Design High-Performing Architectures: 24%
- Design Cost-Optimized Architectures: 20%

Typical trap areas:
- Secure: IAM roles vs IAM users on EC2 (always roles), security group chaining (SG-to-SG, not CIDR), KMS customer-managed keys, S3 encryption options (SSE-S3 vs SSE-KMS vs SSE-C).
- Resilient: disaster recovery tier selection (backup and restore, pilot light, warm standby, multi-site active/active).
- High-Performing: storage class selection (gp3 vs io2, EFS vs FSx for Windows vs Lustre).
- Cost-Optimized: Spot vs Reserved vs Savings Plans vs On-Demand for the workload at hand.

## How the question bank is built

Questions are written against strict rules and reviewed by the founder:

- Scenario-based MCQs, 2 to 4 sentence realistic situations, not trivia.
- Exactly 4 options per question with one correct answer, and an explanation that reasons about each option specifically.
- Sources are verifiable primary documents: PMI Exam Content Outlines, PMBOK 7 principles, AWS Well-Architected pillars, AWS service documentation. No leaked exam material, no verbatim copyrighted text.
- Plain technical language. No marketing cliches (seamless, leverage, comprehensive, robust, empower).
- Correct-answer letter distribution across A, B, C, D is kept near-uniform so users cannot pattern-match.
- Domain weights mirror the real exam: PMP 2021 ECO 42/50/8, PMP 2026 ECO 33/41/26, AWS SAA-C03 30/26/24/20.

Current bank size: 300 questions per active certification (PMP 2021 ECO, PMP 2026 ECO, AWS SAA-C03). Every in-app question has a Report button; reports are reviewed weekly and bad questions are fixed or removed.

## Feature list

- Daily question delivery in Telegram chat via /daily.
- Full Mini App UI inside Telegram, also reachable on the web at passmycert.app/app.
- Spaced repetition using an SM-2 implementation: items answered incorrectly return first; the interval grows with consecutive correct answers.
- Per-domain accuracy tracking.
- Mock exam mode (Ultra and Lifetime only): matches the real exam format (180 Q / 230 min for PMP, 65 Q / 130 min for SAA-C03), scored by domain.
- Streak tracking: one increment per UTC day on practice activity, resets on a gap.
- Daily reminder at a user-chosen UTC hour.
- /claim command to link a web card purchase to a Telegram account.
- Telegram Stars and Lemon Squeezy card checkout.
- Free tier throttle: 5 questions per UTC day.
- Subscription expiry enforced on every API call and by an hourly sweep, so a lapsed paid tier reverts to free automatically.
