One place for students to find practical academic resources and everyday study utilities.
BTechVault is a student-focused study resource platform built to make everyday B.Tech work a little easier. Engineering students often need the same information at different points in a semester: class notes before an exam, previous year question papers while preparing for a test, lab manuals before a practical session, or a quick calculator when checking grades and planning study time. BTechVault brings these resources together in one searchable place instead of making students depend on scattered links and old messages.
The study-material library is organised around the information students actually use, including subjects, branches, academic years, colleges and tags. You can browse available PDFs, open a material page, and save useful resources to your account. Students who have their own notes or material they are permitted to share can also contribute through the upload area. Every contribution should be material the uploader created or has permission to distribute; BTechVault does not encourage uploading pirated textbooks, paid courses, private documents, or copyrighted material without permission.
Alongside the library, BTechVault provides free browser-based student tools. The tools include GPA and grade calculators, a JEE percentage calculator, a study timetable generator, image utilities for applications and projects, and a resume builder. These tools are designed to perform useful calculations or file processing directly in the browser whenever practical, so students can get a result without creating an account just to use a simple utility.
The calculators are intended for planning and educational use. For example, grading systems can differ between colleges, universities and boards, so a calculator should not replace an official academic record or institution-specific rule. The JEE percentage calculator also distinguishes marks percentage from percentile and points users toward official admission information for decisions that depend on current rules.
BTechVault is independently maintained and is not affiliated with a particular college, university, examination authority, or government department. Study materials are shared by students and may contain mistakes or outdated information, so important academic details should always be checked against the relevant official syllabus, notice or institution. If you find an incorrect resource, a broken file, or material that should not be published, please contact the team so it can be reviewed.
The goal is simple: useful study resources should be easier to find, easier to understand, and easier to use. New tools and student-contributed resources can be added over time, while the site continues to focus on practical value rather than unnecessary features.
