Sajha Notes Explained: What Shared Notes Are, How Students Use Them and Where to Find Them for CSIT, BIT and NEB
What "sajha notes" means, why shared notes work for Nepali students, how notesharu organises shared notes and solved past questions for TU BSc CSIT, BIT and NEB Class 11 and 12, and how to use them well without the usual mistakes.

Sajha (साझा) is the Nepali word for shared or common. Sajha notes are the notes students pass to each other: a senior's handwritten summaries, a classmate's solved past paper, a chapter condensed to two pages the night before the exam. In every college and school in Nepal they circulate through photocopies, Messenger groups and PDF folders, and they are often the most used study material of all, because they are written by someone who sat the same paper.
This article explains what makes shared notes useful, what their weaknesses are, how notesharu organises them as a free shared collection for Tribhuvan University BSc CSIT and BIT and for NEB Class 11 and 12, and how to get the most out of them. The collection itself is on the sajha notes page.
Why shared notes work
A textbook explains a subject. A shared note explains the exam. The student who wrote it already knew which three units carry most of the marks, which derivation is asked every year, and how long a 5-mark answer should be. That knowledge is exactly what a first-time student lacks, and it is why a good senior's note is worth more than a chapter of the prescribed book in the last month.
Shared notes also match the paper's language. TU and NEB examiners write questions in a recognisable style, and a note built around past questions uses the same phrasing, so the student recognises the question on the day instead of translating it.
Where shared notes go wrong
The same origin creates the weaknesses. A note written by one student carries that student's errors, and errors spread with every photocopy. Notes written for an old syllabus keep circulating after the syllabus changes. Notes are usually uneven: three units in detail, the rest a page each, depending on what the author found time for. And a scanned photocopy of a handwritten note is slow to read on a phone, impossible to search, and useless for revision cards.
The ideal is shared notes with the strengths kept and the weaknesses removed: written against the current official syllabus, complete across every unit, checked for accuracy, searchable, and in a form that works on a phone. That is what notesharu set out to build.
How notesharu organises shared notes
Everything is organised by the official syllabus, not by whoever happened to write a note. Each program and grade has a page listing its subjects; each subject page shows the official unit tree on the left and the material on the right.
| Program | Subjects | Solved past questions |
|---|---|---|
| TU BSc CSIT | 41 across 8 semesters | 2,766 |
| TU BIT | 43 across 8 semesters | more than 2,400 |
| NEB Class 11 | 14 across Science, Management, Law and common subjects | more than 2,000 |
| NEB Class 12 | 14 across the same streams | more than 2,400 |
That is 112 subjects and 9,686 solved questions in total, all free to read in the browser with nothing to download.
For every subject there are four kinds of shared material:
- Chapter and unit notes: written against the official TU or NEB syllabus unit by unit, in exam-formal English, so that no unit is missing and every topic can be traced back to the syllabus.
- Solved past questions: real questions from previous TU semester papers and NEB board papers, each with a full model answer. Many carry tiered answers at 1-mark, 5-mark and 10-mark depth so you can revise the same topic at the length the paper asks for.
- Important questions: for each subject, a ranked list of the topics that have appeared most often across past papers, which is the "which units matter" knowledge that good shared notes carry.
- Flashcards: short recall cards derived from the answers, reviewed on a spaced repetition schedule when you sign in.
A worked example of how this looks for one subject is the Database Management System page for CSC265, which goes from the syllabus tree to unit notes such as Database Recovery Techniques to the solved questions on that unit. On the NEB side, Class 11 Physics does the same chapter by chapter, for example Thermal Expansion.
How students share and contribute
Sharing on notesharu runs in both directions. Reading is open: notes, syllabus coverage and a large share of the model answers need no account, which is what makes them shareable; a link to a chapter works for everyone in a class group. A free account adds the study tools: progress tracking, flashcards and spaced repetition, and saved favourites.
Students also feed the collection. The question queue on the contact page takes questions that are missing a solved answer, and submitted questions are answered and published for everyone. The NoteTok feed turns individual exam questions into short videos that are easy to pass around. And the scan tool lets a student photograph a question from a paper or a handwritten note and find the matching solved answer, which is the fastest way to check a classmate's note against a model answer.
Using shared notes well
Four habits make the difference between a student who collects notes and one who passes with them.
- Read against the syllabus. Open the unit list first and tick off what you have covered. A shared note that skips a unit does not make the unit disappear from the paper.
- Check frequency before depth. Use the important questions list for the subject to decide which units deserve 10-mark preparation and which deserve a summary. Shared notes written by one student reflect one student's guess; the frequency list reflects every past paper in the collection.
- Write, then compare. For each important question, write your own answer at exam length, then compare it with the model answer. Reading someone else's answer feels like learning and is not.
- Convert to cards. Turn each answer into a few recall cards and review them daily in the last month. Ten minutes of cards keeps the answers available on the day.
The full method, with timings, is in how to use TU past questions the right way, and the semester-by-semester subject guide is in BSc CSIT notes semester-wise.

Shared notes have always been how Nepali students help each other pass. Keeping them complete, accurate and free, and tying them to the official syllabus, is the whole point of the collection.
