Hiraya is your adaptive reviewer for the PhilNITS FE exam — powered by Item Response Theory and spaced repetition, so every session brings you measurably closer to passing.
“The reviewer that studies you— and shows you exactly where to improve.”
Hiraya Adaptive EngineEvery feature is engineered around the PhilNITS FE syllabus — not generic quiz tools repurposed for exams. Hiraya learns your weak spots and targets them precisely, so you study less time but with far greater effect.
Questions adapt in real time to your current ability level using Item Response Theory (IRT). Not too hard, not too easy — always at the edge of your zone of proximal development.
SM-2 algorithm schedules reviews at the optimal moment — right before you'd forget. Retention compounds over time.
Category-by-category ability scores, historical session data, and detailed answer logs so you always know exactly where you stand.
1,480 authentic PhilNITS questions across 9 official exam categories — exactly what you'll face on test day.
Create classes, manage students, and assign targeted practice sets. See each student's ability score at a glance.
Habit-forming streak tracking with XP rewards keeps motivation high through the long study grind before exam day.
A single readiness score tells you how prepared you are. No guessing — Hiraya shows when you're ready to sit the exam.
Beyond past papers — Hiraya generates fresh, syllabus-aligned questions on demand, targeted at the topics you keep missing. Infinite practice, instant explanations.
Switch between Previous Exam (1,480 authentic PhilNITS items) and AI Mode(generated on the fly) in the same session flow. Drill the real thing, then push further when you're ready.
Select a category — from Technology Strategy to Data Structure & Algorithms — or let Hiraya choose based on your weakest area.
Answer questions that adjust difficulty in real time. The engine reads every response to calibrate your ability score and surface the items you need most.
Watch your category scores climb session by session. Hiraya surfaces what's improved and what still needs work — with clinical precision.
Hiraya's adaptive engine combines three proven psychometric and cognitive science methods. Together they build a precise model of what you know — and intelligently close the gaps before exam day.
Each question carries a difficulty parameter. As you answer, Hiraya estimates your latent ability θ using maximum likelihood estimation — and selects the next item at exactly the right challenge level.
Items you answered incorrectly are re-queued at scientifically optimized intervals. Forgetting curves are flattened. Long-term retention is maximized without over-drilling what you already know.
Your ability score is tracked independently for all 9 PhilNITS categories. Sessions automatically prioritize the categories where improvement will have the greatest impact on your overall readiness.
Growing alongside every student preparing for their PhilNITS milestone.
The adaptive questions are no joke. It knew exactly which areas I was shaky on and drilled me there until I actually understood the concept.
I studied with regular reviewers for two attempts and failed both. Two months with Hiraya, I passed. The spaced repetition feature is genuinely different.
I use it to manage my review classes. Assigning targeted practice by category and seeing each student's ability score made my coaching so much more precise.
“Study smart. Rise ready.”
