Every tool here is free, needs no login, and runs entirely in your browser — nothing you type is sent anywhere or stored.

They fall into two groups. Some work anywhere in the world, because the arithmetic is the same wherever you study. Others are built on a specific university’s published regulation, and those pages cite the clause so you can check it.

Works anywhere

Final Grade Calculator — what the last exam has to score for you to finish on the grade you want, plus the best total still reachable and the total you keep if it goes badly.
Weighted Grade Calculator — assignments, mid-terms, labs and finals with their own weights. It also tells you whether your weights actually add up to 100, which most tools quietly hide.
CGPA to GPA Converter — between a 10-point CGPA, a percentage and the 4.0 scale, with a straight explanation of why no official India-to-US conversion exists and what to put on the application instead.
Semester Planner — plan the semesters you have left, credit by credit, and see where your CGPA actually lands.

Marks and grades

CGPA Calculator — SGPA and CGPA from your subjects, credits and grades, plus percentage conversion. Start here if you’re not sure which you need.
SGPA to CGPA — enter one semester for SGPA, or every semester together for CGPA. Uses JNTUH clause 9.8.
CGPA to Percentage — with an honest explanation of why there is no single national formula, and how to find your university’s.
Percentage to CGPA — the reverse conversion. Useful for working out what CGPA a 60% or 70% job cut-off means.
CGPA to Percentage Table — the whole chart, every value from 4.0 to 10.0, calculated from the regulation rather than typed out. Each row is linkable.
JNTUH CGPA Calculator — built specifically on the R22 regulations, with the official grade table and a quick reference chart.

The conversion formulas come from JNTUH’s own published academic regulations, with the clause cited on each page. If you’re at a different university, each page explains how to find your correct rule rather than assuming one.

Planning ahead

Target CGPA Calculator — the inverse of the others. Tell it the CGPA you want and it works out the average grade point you need across your remaining credits, or tells you honestly that the target has stopped being reachable.
Pass Marks Calculator — how much you need in the semester end exam, from your internals. It also tells you the thing nobody else will: when the internal minimum has already decided the subject.
Backlog Planner — given the credits you are short by, the fewest subjects you can clear to close the gap.
JNTUH Promotion Calculator — whether your secured credits clear the clause 7.3 threshold for the next year, and if not, exactly how many credits short you are.

Attendance

Attendance Calculator — your current percentage, how many classes you can still miss at 75%, and how many you’d need to attend consecutively to recover. The recovery number is the one most students underestimate.

Entrance and competitive exams

GATE Score Calculator — the formula from the official brochure, plus an honest range around the one value GATE never publishes. Most calculators hide that they picked it for you.
EAMCET Rank Predictor — estimate your rank from your marks.

For GATE CSE specifically, I also build Quorank — free practice on previous year questions marked by the real GATE rules, plus a rank predictor that takes over where the score calculator stops. Same author, same policy on sourcing.

University-specific conversions

Each of these uses that university’s own published formula, with the clause quoted. They are separate pages rather than one page with a dropdown, because the grade tables, pass rules and attendance requirements genuinely differ — and mixing them up is how students end up putting a wrong percentage on a job application.

JNTUK — R23, clause 19, plus the promotion rule that is a percentage rather than a fixed credit count.
VTU — 2021 scheme, clause 21OB12.2, and why the 2022 scheme changes everything.
Anna University — Regulation 2023, clause 21.10, and a pass rule stricter than most.

Writing your resume

There is no resume builder here, deliberately. The resume guide covers what Indian recruiters actually filter on — which matters far more than the template you start from.

A note on accuracy

Academic formulas on this site are taken from the issuing university’s own regulations, and the source is linked on the page so you can check it yourself. Where a formula could not be verified from an official document, it is labelled as unverified rather than presented as fact.

The same rule applies in reverse. On the CGPA-to-GPA page there is no official formula to cite, because none exists — so the page says that plainly instead of printing a number and hoping you don’t ask.

That said, these are planning tools. For anything formal — a job application, a higher-studies form — use the figures printed on your official marks memo.
