About
Certification prep deserved better software
Every year, hundreds of thousands of students sit English certification exams — Michigan, Cambridge, LRN. The certificates matter: university admissions, public-sector hiring, careers. Yet preparation still mostly means photocopied past papers, essays that come back marked a week later, and a speaking section you first experience on exam day.
certifyboost started from a simple observation: the technology to fix all of this already exists. Timed digital mocks scored against published bands. AI that grades an essay on the exam's published criteria in a minute. A speaking examiner you can practice with at midnight before the exam. Streaks and XP that turn “I should study” into “I studied every day this month.”
We build for the students sitting these exams and the teachers who prepare them — with pricing that respects the fact that exam prep is a season, not a subscription for life.
Principles
How we build
Fidelity to the real exam
Every mock mirrors the published structure, timing and scoring of its certification. If the real listening plays once, ours plays once.
AI where it earns its place
We use AI for what humans can't scale — instant essay bands, speaking interviews on demand — and deterministic scoring everywhere else.
Honest with students
A generous free tier, a pass that expires instead of auto-renewing, and analytics that tell you the truth about your readiness.
Preparing for an exam? Teaching a class?
Either way, the fastest way to understand certifyboost is to use it.
