01 · Context
Prepo prepares CSE graduates for government IT jobs in Bangladesh, in Bangla.
- It covers CSE posts in BPSC non-cadre exams, bank IT and the power sector.
- Past exam questions, lessons by topic, mock tests and job circulars live in one place.
- No fees and no ads. Questions, lessons and circulars open without an account.
02 · Problem
Preparing alone, people get stuck in the same few places.
- The syllabus is big, and it’s hard to know where to start.
- What you read is gone by the time you sit the exam.
- Nobody is around to ask when a maths problem gets stuck.
- Circulars slip by, and the deadline is noticed only after it passes.
03 · Research
I started from the moments people give up, not from a feature list.
- I designed for someone preparing alone, with no coach to say what to study next.
- Each feature answers one of their questions: where do I start, why do I forget, who checks my answer, when is the deadline.
- Bangla first, so explanations read the way people think, with English one tap away.
- Free and open without an account, so trying it costs nothing.
04 · Design
Each stuck point gets one feature, in plain Bangla.
- A syllabus map that changes colour as topics are learned, with a weekly plan up to the exam date.
- Wrong answers come back after 1, 3, 7, 16 and 35 days until they stick, with flashcards and one-line memory aids.
- Every circular is checked against the original notice, with age and degree matching and deadline reminders.
- Written answers, typed or photographed, are checked point by point next to a model answer.

05 · Build
A Vue app on Firebase, with AI for the hard questions.
- Nuxt and Vue for the app, with a ⌘K search and a Bangla and English interface.
- Firebase for the data, multi-role access, real-time chat and calling, and push reminders before a deadline.
- AI on Gemini and Groq checks written answers and explains solutions step by step in Bangla.
06 · Launch
Live at chakri.uxatom.com (opens in a new tab), free and without ads.
- Study groups, a live mock test every Friday and 10-question duels with a friend.
- Push reminders before a circular’s deadline, and notices when admit cards or results come out.
07 · Growth
Remove every reason not to try it, then let friends bring friends.
- Free, no ads, and questions, lessons and circulars open without an account.
- Bangla first, with technical terms kept in English, the way people actually study them.
- A 10-question duel is sent to a friend as a link, and study groups grow the same way.
08 · Results
One place for the whole preparation, instead of scattered groups and files.
- So far: 759 published questions, 63 topics with lessons and 12 open circulars.
- Every stuck point from the problem has a working feature, from the syllabus map to answer checking.
- Anyone can start in seconds: questions, lessons and circulars open without an account.
09 · Reflection
Building alone, every feature has to earn its place.
- AI helps most where people are stuck alone, like a maths step or a written answer, not everywhere.
- Trust comes from checking: a circular is only shown after it matches the original notice.
- Next, I’ll measure which features people come back to and grow the question bank topic by topic.
