About

This repository is a personal study vault and practice workspace for the BSc.CSIT 6th semester curriculum of Tribhuvan University (TU), Nepal, compiled by Adarasha Gaihre (aakku106).

It brings together three things into a single organized space:

• 📚 Course notes & syllabi — structured Obsidian notes per subject with official syllabus breakdowns.
• 🗂 Past exam papers (Old Sets) — scanned/typed TU question papers organized by Nepali Bikram Sambat (BS) year.
• 💻 .NET practice code — independent C# / .NET projects written while studying the .NET-Centric Computing subject.

Note. This is a study/learning repository, not a shipped application. The code here is teaching snippets and scratch practice. The repo may not contain notes for every topic of every subject — course content and syllabi evolve, and notes are not guaranteed to be current. The owner holds no rights to third-party content included (past question papers, syllabus sources, reference PDFs).

Semesters & Subjects

The 6th semester covers six subjects, each with its own course directory and an Obsidian "hub" note at the repo root:

All hub notes link back to the master hub BSc.CSIT.md. Notes use Obsidian conventions (YAML frontmatter + [[wikilinks]]) — open the repo as an Obsidian vault to get the full cross-linked reading experience.

The "What to Read" (Exam Analysis)

The highest-signal documents in the repo are the exam-analysis notes — topic-wise frequency analyses of every past exam set, with priority tiers that say what to study first. When reviewing the material, these are the best starting points:

• Software Engineering → SE/EXAM.md
• Technical Writing → TW/EXXAM.md (note the intentional double-X filename)
• Compiler Design & Construction → CDC/InternalExams/Exam.md

📘 Subject Highlights

Compiler Design & Construction (CDC/)

Covers the classic compiler pipeline: introduction, lexical analysis (the bulk of the syllabus), symbol table & runtime storage, and intermediate code generation / optimization / case studies. Includes 8 past-paper sets and an exam analysis with priority tiers.

.NET-Centric Computing (DOTNET/)

The most hands-on subject. The syllabus spans language preliminaries → ASP.NET Core → MVC → databases → state management → client-side development → security → hosting. The code directory contains five independent projects used to practice these concepts (see .NET Projects below), plus lab task descriptions and code.

E-Commerce (E-Com/)

E-commerce fundamentals: business models, electronic payment systems, building e-commerce systems, security, digital marketing, and optimization. Includes 5 past-paper sets.

E-Government (E-Gov/)

Concepts and models of e-governance, infrastructure development, security, data warehousing/mining in government, and case studies. Includes 7 past-paper sets (the latest, 2082, plus a model set).

Software Engineering (SE/)

A full 10-unit sweep: processes, agile, requirements engineering, system modeling, architecture, design, testing, evolution, and management. Ships with a detailed exam-analysis document and 7 past-paper sets.

Technical Writing (TW/)

Practical writing across 12 units: audience & purpose, the writing process, brief correspondence, document design, web writing, employment communication, presentations, recommendation reports, proposals, and workplace ethics. Includes 8 past-paper sets.

💻 .NET Projects

Each project is an independent .csproj targeting net10.0. There is no solution file (.sln) and no shared root build.

# Build a single project (run from inside its directory)
cd DOTNET/Day1 && dotnet build

DB note. LearnDB/Program.cs reads the connection string from the POSTGRES_CONNECTION_STRING env var (defaulting to Host=localhost;Port=5432;Database=postgres;Username=$USER), uses EnsureCreatedAsync (no migrations), and validates via CanConnectAsync. A "PostgreSQL connection failed" warning is expected unless a local Postgres is running — the safe fallback is intentional, not a bug.

🧰 Toolchain & Requirements

• .NET 10 SDK (net10.0 target). The repo was developed on dotnet --version 10.0.301.
• Build is the only verification step — there is no lint / test / CI configuration in this repo.
• Obsidian Vault — for best note-navigation experience, open the repo root in Obsidian.

🗂 Past Exam Papers (Old Sets)

• Organized in each course's Old_sets/ directory, named by BS year (e.g. 2076.md → exam from 2076 BS).
• Some folders include Model papers (Model.md, Model_I.md, Model_II.md) — practice sets modeled on the real exam format.
• Papers typically follow the TU structure of Section A / Section B questions.
