The mark you need, per subject
Both pass conditions, not one: the 40% separate end-semester minimum as well as the combined total. Spreadsheets miss the first, which is how a subject that “looked passed” comes back as a supplementary.
Every other tool tells you what you already scored.
This one tells you what you still need.
Three ways into one record — your semester, your attendance, and Tex, which answers in your own words and shows the working. If your college runs etlab, it works for you.
Free for students, forever — written into the licence.
Your record is a file on your own machine, and no account is needed
to use any of it — except Tex, whose sign-in is capped while
it is in testing.
RegulationR 7.5.ii
76% attendance is not “fine”. It is two marks you have already lost.
Under Regulations 2024, attendance is not only an eligibility gate — it is a scored component of your internal marks, worth up to 5 of them, in every subject, in bands. Full marks start at 85%.
So a student sitting comfortably above the 75% line is still forfeiting marks, in every subject, quietly, all semester. No portal shows this. Nothing else computes it. It is the single largest number most students never see.

R 7.5.ii
And below 60%, the door shuts. R 6.2 lets the Principal
condone attendance under 75% only as far as 60%. Below that the exam
cannot be sat, and attending from there on does not change it. TargetX
says so on the day it becomes true — not after results.
What itdoes
How many classes you can still miss
Computed from real attended-over-held counts, with duty leave credited the way R 6.3.ii actually caps it — at 10% of classes held, which grows as you spend it. Answered as a number of classes, not a percentage.
The cheapest route to your CGPA
Name a target. TargetX works backwards to the SGPA each remaining semester has to carry, then to which subject is cheapest to push and how far — balanced so the plan is one a person can actually attempt, rather than four subjects at 95.
Your marks, in without typing them
Sign in to your college’s etlab portal and it pulls every semester, attendance, series marks, grades and published SGPA in one pass. Your password is used for that one request and never stored — or skip it entirely and type things in by hand.
Your college’s rules, not just KTU’s
It ships set to Regulations 2024, checked against the document rather than copied from another calculator. But the numbers are not welded in: the grade bands, the pass mark, the separate exam minimum, the attendance you need and what attendance is worth all live in a profile you can copy and edit. If you are at an autonomous college, set yours once and every figure after that is computed against your rules. The built-in profile is marked checked; one you have edited is marked not checked, everywhere it appears.
And a profile travels. Whoever reads the regulations once exports theirs and hands the text to the rest of your course. It carries rules and nothing else — no marks, no attendance, no name — and it cannot arrive claiming to be checked, because that flag is never read off a file. You get the numbers, and you get to know who sent them.
The same record on a phone, same engine underneath — one arithmetic, not a cut-down second version of it. The Android build is out. It is an .apk in the table below, sideloaded rather than from Play — the notice under the table says what your phone will ask you first.
A note fromRishi
I built this because of one number.
I was sitting at 76% attendance and thought I was fine. Everyone says 75 is the line. Then I actually read Regulations 2024 and found R 7.5.ii — attendance is not only the eligibility gate, it is worth five internal marks, in bands. At 76% I had already given away two of them. In every subject. All semester. And nothing had told me: not the portal, not any of the calculators, nobody.
That annoyed me enough to build this. Then it turned into a thousand tests, because once you are the thing telling people what they need to score, being approximately right is not good enough.
This release, 0.5.0, is the last one built on etlab sync. Not because it broke — it works better than it ever has. Your college’s rules can now be written once and passed to everyone else on your course, Tex answers you properly instead of silently jumping you to a screen, and the things students reported are fixed in it.
The real reason is harder to say out loud. To keep working on this I would need someone to pay for it, and the only people who could are colleges — and no college is ever going to buy software that logs into their portal with their students’ passwords. They would be right to refuse. I would refuse. On top of that, the whole thing can be switched off on any ordinary afternoon by someone at etlab who has never heard of me, and there would be nothing I could do about it. That is not a foundation. I would rather say so than let the repo go quiet and have you work it out yourselves.
And honestly, the questions I have started caring about are on the other side of that wall anyway. Which students are about to lose exam eligibility, while there is still time to fix it. What a whole class is struggling with, not just me. Whether the internal marks a college submits to KTU are even correct. None of that is reachable from one student’s login, and all of it matters more than a number on my own screen.
So I am going to go and build that properly — with a college’s own data, and its own permission, instead of around it. The regulation engine underneath this app is the part that took longest and is tested hardest, and it is the part that comes with me.
- You lose nothing
- This build keeps working for as long as your portal does. Free, on your own machine, and written into the licence rather than promised — so it was never something I could quietly take back.
- Still tell me if a number is wrong
- A figure that disagrees with your portal is still a bug, I still want to know, and the engine it lives in is the one I am carrying forward. Reporting it now helps the next thing too.
I wanted to know what I needed to score, and the portal would not
tell me. That question is answered now, and the answer is yours to
keep.

A desktop app — Windows, macOS and Linux. It installs for your user account only, so it needs no administrator rights, and it runs entirely offline apart from the portal you point it at.

There is no iPhone version, and there is not going to be
one. Apple desktops are covered by the .dmg above; it is the
phone that is missing. An iPhone runs only what Apple has signed, and
Apple signs for members of its Developer Program, which costs $99 a
year. It is rent. The year the payments stop, the app stops installing
for everyone who has it. TestFlight is not a way round it either: a
build uploaded there stops opening 90 days later, so a student would
lose the app four times a year and have to be re-invited each time.
Everything on this page is a file you download and keep. iOS has
nothing of that shape. Android does: the build is on the release
page now, listed above.
Android will warn you before installing this. It is
not sold through Google Play, so the phone treats it as coming from
an unknown source and asks you to allow it once, for the app doing
the installing — usually your browser. That prompt is Android
working correctly, and you should be suspicious of any app that tells
you to turn the warning off and move on. What you can check instead is
that the file is the one that was built: every release publishes the
APK’s SHA-256 beside it, and any file manager or
Termux can print the same figure for the file you
downloaded. The app is signed with a 4096-bit key held by the person
who wrote it, which is what lets your phone confirm that a later
update came from the same place — and is why an update signed
by anyone else will be refused rather than quietly installed.
Windows may refuse to download this. The installers
are not code-signed, so Windows has nothing to identify the publisher
with and falls back to reputation — which a new file with few
downloads does not have. Usually that is SmartScreen asking you to
choose More info, then Run anyway. Sometimes Defender
is blunter and blocks the download outright, or deletes the file after
it lands. If that happens, the .msi on the same
release page goes through Windows Installer and is flagged far less
often; it installs for the whole machine, so it asks for administrator
rights, which the .exe deliberately does not. Rather than ask you
to take any of that on trust, every release publishes
SHA256SUMS-<platform>.txt beside the installers, so
you can check that what you downloaded is what was built. In
PowerShell:
Get-FileHash .\TargetX_<version>_x64-setup.exe -Algorithm SHA256
A certificate is on the list. A checksum proves the file did not
change in transit, not who built it — it is not a substitute, and this
page will say so until one is bought.
macOS will refuse to open it outright. The build is
not notarised by Apple, so Gatekeeper does not offer a way through —
it reports that TargetX is damaged, or that the developer cannot be
verified, and stops. It is neither; that is the message macOS gives
any unnotarised app. Open System Settings → Privacy &
Security, scroll to the note about TargetX being blocked, and
choose Open Anyway. If it does not appear there, clear the
quarantine flag the browser attached:
xattr -dr com.apple.quarantine /Applications/TargetX.app
Check the SHA-256 above first. Running that command on software you
have not verified is exactly how the protection is meant to be used
against you, and it is worth being suspicious of any page that tells
you to type it — including this one.
Updates are signed, even though the installer is not.
A few seconds after launch the app checks whether a newer version
exists, and asks you before doing anything about it. What it downloads
has to carry a signature made with the key your copy was built to
trust. If it does not match, the file is thrown away and nothing is
installed.
Where yourdata lives
On your machine. That is the whole answer.
Your marks are a file in your own user profile. Nothing about them is transmitted anywhere, and there is no telemetry, no analytics and no crash reporting — the app makes network requests to exactly four places, and the fourth only if you choose to sign in:
- github.com
- Once on launch, to ask whether a newer version exists. Block it and the app works unchanged.
- raw.githubusercontent.com
- Once on launch, to refresh the KTU course catalogue, so a curriculum revision does not need a new build.
- Your college portal
- Only when you press Sync, and only to the address you typed. Your password is held for the length of that one request — never written to disk, never put into the saved record, never in the export, never in a log.
- The question box
- Only if you sign in, and only for a question the app could not answer by itself — most are answered on your machine and never leave it. What is sent is your question and the code and title of your subjects. No marks, no attendance, no CGPA, no name, no register number. What comes back is a destination, not an answer: one of five screens, or one of your own subjects, and anything else is rejected. Every figure you then read was computed here.
Sync has been proved against one college’s etlab so far.
If yours lays its pages out differently, the sync fails and shows you
what it could not read rather than recording half a semester. You can
check whether it will work without giving anyone an account:
save your academics page from a browser you are already signed in to,
and drop the file onto Data → “Will sync work at my college?”.
The page never leaves your machine; what the app offers you to send is
a separate block of table shapes with every digit blanked out.
Forcolleges
Students never pay. Institutions do.
TargetX is licensed under BUSL-1.1, and the right of an individual student to use it free, forever, is written into the licence rather than offered as a policy that could be withdrawn. Deploying it across an institution is a commercial use.
- Install scope
- Per user, not per machine — no administrator rights, and a student’s academic record stays out of a shared location on a lab machine.
- Silent deployment
- NSIS /S and msiexec /qn, for Intune, SCCM or a login script.
- Reads only
- The app has no code path that writes to a portal. The session cookie lives in the native process, where nothing in the web layer can reach it.
- The detail
- DEPLOYMENT.md answers “what is this and what does it touch?” — every claim on this page is checkable there against named files.
Somethingwrong?
A wrong number is a bug, and it is worth reporting.
TargetX has been proved against one college’s portal and one set of regulations read carefully. Neither of those is the same as being right everywhere. If a figure it shows you disagrees with what your college recorded, the college is right and this is a defect — and it is one worth knowing about, because the same arithmetic runs for everyone.
Report a problem
GitHub issues
What makes a report actionable. The subject code, the
figure TargetX showed, the figure you expected, and where the real one
came from — a portal page or a grade card. If a sync failed, the app’s
Data screen names the log file; its contents are error messages and
nothing about your marks, and you can read it before you send it.
Never paste your portal password into an issue, and
blank out your roll number: an issue is a public page.
Questions and “will this work at my college?” belong in discussions rather than issues. Security problems should not be filed in public at all — use GitHub’s private advisory form, which is only visible to the maintainer.
