Nobody teaches this part. School gets you to the +2 result and then stops, and the admission process that follows is a sequence of portals, deadlines and documents that you are expected to already understand. It is not difficult, but it is unforgiving about order and timing, and most of what goes wrong is a step taken too late rather than a step done badly.
The one-line version: collect the documents before the results come out, register on the university's entrance portal as soon as the notice appears, pay before you submit, and keep every deadline in a calendar. Everything else follows from those four.
What are the steps, in order?
The shape is the same across Tribhuvan University's faculties — CSIT through the Institute of Science and Technology, BCA through Humanities, BIT, management through CMAT, engineering through IOE — even though each runs its own portal and its own dates.
Step one is the one students skip and then regret. Documents take days to produce and your college is dealing with your whole batch at once; starting that after the result is how a week disappears from a three-week application window.
What documents do you need?
The core set is consistent across TU programmes. Get two or three photocopy sets made at the same time, and keep the originals together in one folder you do not lend to anyone.
Requirements do shift between campuses and cycles, so read the admission notice for the specific programme rather than treating any list, this one included, as final.
Most of what goes wrong is a step taken too late, not a step done badly.
Why the migration certificate catches people out
If you did your Class 12 under the National Examination Board and you are joining a Tribhuvan University programme, you are moving between boards, and the migration certificate is the document that records it. Colleges commonly ask for the original rather than a photocopy, which means you cannot hand the same one to two colleges.
That has a practical consequence worth planning around: if you are holding a seat at one college while waiting for a better list elsewhere, your original may already be sitting in the first college's file. Ask what their process is for returning it and how long that takes, before you hand it over rather than after.
One form, many colleges
A thing students routinely get wrong by applying several times: for TU programmes a single entrance form covers every affiliated college running that programme. You are not applying to a college at this stage, you are applying to the programme, and the college comes later through the priority form and the merit list.
That is why the shortlist matters before the entrance rather than after it. By the time the priority form opens you will have days, not weeks, to decide an order you will live with for four years, and that is a bad moment to start researching fees.
What happens after the result
You get a rank, not a college. You then submit a priority order of colleges on the same portal, the university publishes a merit list, and seats are allocated against your list in rank order. Lists run in rounds, so a seat you did not get on the first can open on a later one as students above you take something else.
Two things about this stage. Your priority list is taken literally, so never put an option above one you would actually attend. And missing the counselling slot or the payment deadline after a seat is allocated forfeits it — there is no informal route back, and nobody telephones to remind you.
If your Class 12 was not from NEB
A CBSE, A Level or other non-NEB qualification needs an equivalence certificate before you can be admitted, obtained through the board at Sanothimi. This is the single longest lead time in the whole process and it does not speed up because you are in a hurry.
Start it the moment you have your result, not when a college asks for it. Students on foreign boards lose seats to this every year — not because they were ineligible, but because the certificate arrived after the admission window closed.
The short answer
Treat this as an administrative project with deadlines, because that is what it is. Get your documents together before the result, start any equivalence immediately, register on the portal the day the notice appears, pay before you submit, print the admit card properly, and build your college shortlist before the priority form opens rather than during it. The entrance measures what you know. Everything around it measures whether you were organised.
