Every engineering team runs on Git, yet most students meet it as a pile of half-remembered commands. This course builds the three-area mental model (working tree, staging area, repository) and then layers the skills you will actually use daily: clean commits, branching and merging, pull requests, remotes and forks, stash and cherry-pick, bisect, hooks and reflog recovery.

Short lessons, real command sequences, and a final exam with certificate eligibility. Free forever — Git is infrastructure for your whole career.

**Who this is for:** first-years through final-years in every branch, and anyone about to join a team that uses GitHub.

**What you need:** a machine with Git installed (or a GitHub account to follow along in the browser).

From first commit to confident collaboration — snapshots, branching, PRs, hooks and disaster recovery

Git & GitHub Mastery

Every product has a web interface, and every product team needs people who can build one properly. This bootcamp covers the foundation the frameworks assume you already know: semantic HTML, the CSS box model, flexbox and grid, modern JavaScript with the DOM, accessible forms, REST API integration and a performance workflow with the browser DevTools.

Eight lessons across four modules. Every lesson follows the nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a server-graded quiz and a one-screen summary. A 30-question bank feeds a 15-question timed final exam; passing earns a verifiable TieEdu certificate.

**Who this is for:** students who have copied tutorial code but cannot yet build a page from scratch, and anyone preparing for a junior frontend interview. The course deliberately teaches the platform (HTML/CSS/JS) before any framework, so React or Vue later becomes an acceleration rather than a crutch.

**What you need:** a browser and a text editor. A free hosting account (GitHub Pages, Netlify or similar) is recommended for the project so you finish with a live URL, not just local files.

HTML, modern CSS, JavaScript, forms, APIs and performance — the frontend stack every product team hires for

Web Development Bootcamp

Every campus placement and off-campus OA opens with an aptitude round. A learner who clears it reaches the coding round; one who does not never sees it. This course teaches exactly the topics that appear - no filler, no "advanced" chapters that never show up in an actual OA.

Eight lessons across four modules: number system and HCF/LCM, ratio-partnership-mixtures and profit-loss, speed-trains-work, then the reasoning half - series, coding-decoding, blood relations, direction sense and syllogisms. Every lesson uses the same nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a quiz and a one-screen summary.

**Who this is for:** any student, any branch, preparing for TCS NQT, Infosys, Wipro, Capgemini, Cognizant or any other company whose OA starts with quant. Also useful for GATE/PSU prelims and bank exams.

**What you need:** class-10 arithmetic. No calculator needed - every technique is taught for mental or rough-paper calculation.

Clear the OA round - the highest-frequency quant and reasoning topics from TCS, Infosys, Wipro and Capgemini, taught with the shortcuts that save minutes

Aptitude & Reasoning Mastery

Every internship report, placement spreadsheet and lab record eventually lands in Excel — and almost nobody was actually taught it. This is the three-hour version: the grid and the data types that silently break totals, the formulas that cover most real work, tables and charts that answer questions honestly, and the five-step clean-up pass for any CSV you did not create.

It ends with a capstone you can defend in an interview: a two-sheet attendance-and-fees tracker with live SUMIFS, an IF status column inside a real Excel Table, and one honest chart. The certificate is issued for that file, not for notes about it.

**Who this is for:** any student, any branch, who has ever pasted data into Excel, squinted at a total that was slightly wrong, or been handed a "report template" with no idea which formulas to trust.

**What you need:** Excel, LibreOffice Calc or Google Sheets (the formulas and shortcuts are identical). No prior spreadsheet knowledge.

Three hours from pasted data to a defensible tracker — formulas, charts and the clean-up pass that fixes other people's exports

Excel for Students

Linux shows up everywhere: lab machines, cloud VMs, CI runners and almost every backend interview. This course teaches the shell you actually use — navigation and permissions, the grep/sed/awk pipeline that beats any GUI for logs, processes with kill and systemd, packages, SSH and network checks, then enough bash to automate the boring half of your day.

Eight compact lessons, each with a worked example you can type along, a practice prompt and a server-graded quiz. Finish with the timed final exam and a verifiable TieEdu certificate.

**Who this is for:** first-years who have only used Windows, placement candidates facing Linux rounds, and anyone deploying a project to a cloud box for the first time.

**What you need:** any Linux sandbox, WSL, or a free cloud VM. Commands are written so you can also follow along on a school lab machine.

Navigate the filesystem, filter text like a pro, manage processes and write your first real bash scripts

Linux & Shell Basics

Every engineering branch starts from the same mathematics. This course covers the Year-1 syllabus that AKTU, VTU and MU curricula share: limits and continuity, series expansions, applications of derivatives, integration and its uses, and the linear algebra that later semesters assume without re-teaching.

Eight lessons across four modules. Every lesson follows the nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a server-graded quiz and a one-screen summary. A 30-question bank feeds a 15-question timed final exam; passing earns a verifiable TieEdu certificate.

**Who this is for:** first-year students of every branch who want the maths to click once, properly, rather than re-deriving it under exam pressure each semester. Also useful for GATE/PSU aspirants revisiting the basics.

**What you need:** class-12 calculus and basic algebra. A pen and paper for the worked examples — these are not spectator topics.

The Year-1 maths every branch shares — limits and series, optimisation, integration, matrices and eigenvalues, taught with the exam shortcuts that save minutes

Engineering Mathematics I

Every software role — backend, data analyst, full-stack, even ML engineering — screens with SQL. This course takes you from writing a first SELECT to designing normalised schemas, choosing indexes that actually get used, reasoning about transactions, and using window functions for the analytics queries that appear in real take-home tests.

Eight lessons across four modules. Every lesson follows the nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a server-graded quiz and a one-screen summary. A 30-question bank feeds a 15-question timed final exam; passing earns a verifiable TieEdu certificate.

**Who this is for:** any student or working developer who wants SQL to be a strength rather than something to google under deadline pressure. Campus OA database rounds, analyst interviews and backend screens all draw from the same pool of patterns taught here.

**What you need:** basic programming familiarity helps but is not required. A free PostgreSQL or MySQL instance to practise on is recommended — these are not spectator topics.

Query, join, aggregate, design and tune the database every placement test and production service depends on

SQL & Databases Mastery

You do not need more projects to get an interview. You need the projects you already have to survive a six-second skim and a keyword search.

This is the shortest course on TieEdu on purpose. Four modules, eight lessons, two hours. It takes a resume that lists duties and turns it into one that leads with outcomes; it makes that resume readable by the applicant tracking systems that filter most online applications; and it rebuilds your LinkedIn so a recruiter searching "react intern" actually finds you.

By the end you will have a one-page resume you can defend line by line, a LinkedIn profile that is a searchable version of it, and a tracking sheet so your application season is a process instead of a hope.

**Who this is for:** any student, any branch, any year — who has applied to something and heard nothing back, or who has never applied because the resume felt unfinished.

**What you need:** your existing projects, even the tutorial ones. We will rebuild two of them into resume material.
