Expected exam schedule:
- Exam dates: Likely to start from last week of April 2026
- Official timetable: Usually released 2-3 weeks before exams
- Check coe1.annauniv.edu for official updates

Important things to keep track of:
- Hall ticket download dates
- Internal marks submission deadline
- Exam fee payment last date
- Revaluation application window after results

Preparation tips for scoring 90+ in each subject:

1. Start with previous year question papers - Anna University often repeats patterns. Solve at least 5 years of papers.

2. Focus on Part A (short answers) - These 10 marks are the easiest to score. Memorize key definitions and formulas.

3. Choose your Part B questions wisely - You usually have choice. Practice the topics you're most comfortable with.

4. Write neatly with diagrams - Presentation matters. Use headings, bullet points, and labeled diagrams.

5. Time management - Allocate time per question and stick to it. Don't spend too long on one question.

6. Group study for tough subjects - Teaching others helps you understand better.

What is RAG?
RAG combines a retrieval system (vector database) with a language model. Instead of relying solely on the LLM's training data, it retrieves relevant documents and includes them in the prompt.

Tech stack:
- Python 3.11+
- LangChain (orchestration)
- ChromaDB (vector database)
- OpenAI or Ollama (LLM)
- Sentence Transformers (embeddings)

Step-by-step process:

1. Load your documents (PDF, text, web pages)
2. Split them into smaller chunks
3. Generate embeddings for each chunk
4. Store embeddings in ChromaDB
5. When user asks a question, find similar chunks
6. Pass the retrieved chunks + question to the LLM
7. LLM generates an answer based on the context

Quick code example:
Code:

from langchain.document_loaders import PyPDFLoader
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.embeddings import HuggingFaceEmbeddings
from langchain.vectorstores import Chroma
from langchain.chains import RetrievalQA
from langchain.llms import Ollama
# Load and split
loader = PyPDFLoader("your_document.pdf")
docs = loader.load()
splitter = RecursiveCharacterTextSplitter(chunk_size=500)
chunks = splitter.split_documents(docs)
# Create vector store
embeddings = HuggingFaceEmbeddings()
db = Chroma.from_documents(chunks, embeddings)
# Query
llm = Ollama(model="llama3")
qa = RetrievalQA.from_chain_type(llm=llm, retriever=db.as_retriever())
result = qa.run("What is this document about?")
print(result)

What is SGE?
Google now shows AI-generated summaries at the top of search results for many queries. This means users may get answers without clicking through to your website.

Impact on organic traffic:
- Informational queries see 20-30% less click-through
- Long-tail keywords are more affected
- Featured snippets are being replaced by AI answers
- Commercial and transactional queries are less affected

How to adapt your SEO strategy:

1. Focus on E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
2. Create content that AI cannot easily replicate - original research, case studies, personal experiences
3. Optimize for "source citations" - SGE cites sources, make sure yours is cited
4. Build topical authority with content clusters
5. Invest in brand building so users search for you directly
6. Diversify traffic sources - email lists, social media, communities

Content types that still get clicks:
- Detailed tutorials with code examples
- Tools and calculators
- Community discussions and forums
- Product comparisons with real testing
- Video content

1. Using a generic objective statement
Bad: "Seeking a challenging position in a reputed company."
Good: "Frontend developer skilled in React and TypeScript, looking to build scalable web apps at a product company."

2. Listing responsibilities instead of achievements
Bad: "Worked on the login module."
Good: "Built a JWT-based authentication system reducing login errors by 40%."

3. Including irrelevant personal details
Remove: Date of birth, father's name, marital status, passport number
Keep: Name, email, phone, LinkedIn, GitHub, portfolio link

4. Poor formatting and inconsistency
- Use a single clean font (Inter, Calibri, or Arial)
- Keep it to 1 page for freshers
- Use consistent date formats
- Ensure proper spacing and alignment

5. Not including project links
Always add:
- Live demo links
- GitHub repository links
- Screenshots or video demos

Recommended resume structure for freshers:
1. Contact Info
2. Summary (2-3 lines)
3. Skills (categorized)
4. Projects (with links)
5. Education
6. Certifications

1. What is the Virtual DOM and how does React use it?
The Virtual DOM is a lightweight copy of the actual DOM. React uses a diffing algorithm to compare the previous and current virtual DOM, then updates only the changed parts in the real DOM.

2. Explain the difference between useState and useReducer.
useState is for simple state, useReducer is for complex state logic with multiple sub-values or when next state depends on previous.

3. What are React Server Components?
Components that render on the server and send HTML to the client. They reduce bundle size and improve performance.

4. How does useEffect cleanup work?
The cleanup function runs before the component unmounts and before the effect re-runs.

5. What is React.memo and when should you use it?
A higher-order component that prevents re-renders if props haven't changed. Use for expensive render components.

6. Explain Context API vs Redux.
Context is built-in and good for low-frequency updates. Redux is better for complex global state with middleware support.

7. What are custom hooks?
Reusable functions that extract component logic. They start with 'use' prefix.

8. How do you handle error boundaries?
Class components with componentDidCatch and getDerivedStateFromError methods.

9. What is code splitting in React?
Using React.lazy() and Suspense to load components on demand.

10. Explain the useCallback vs useMemo difference.
useCallback memoizes functions, useMemo memoizes values.

What are microinteractions?
They are small, contained product moments that revolve around a single task - like toggling a switch, pulling to refresh, or hovering over a button.

Key elements of a microinteraction:
1. Trigger - What initiates the interaction (user action or system event)
2. Rules - What happens during the interaction
3. Feedback - How the user knows something happened
4. Loops & Modes - What happens over time

Examples that improve UX:
- Button hover states with subtle scale/color transitions
- Skeleton loading screens instead of spinners
- Pull-to-refresh with custom animations
- Form validation with inline error messages
- Toggle switches with smooth state transitions
- Heart/like animations on social media

CSS example for a button hover:
Code:

.btn {
  transition: transform 0.2s ease, box-shadow 0.2s ease;
}
.btn:hover {
  transform: translateY(-2px);
  box-shadow: 0 4px 12px rgba(0,0,0,0.15);
}

Server-Side Rendering (SSR)
- Pages rendered on every request
- Best for dynamic, personalized content
- Set with: export const ssr = true;

Static Site Generation (SSG)
- Pages pre-rendered at build time
- Best for blogs, docs, marketing pages
- Set with: export const prerender = true;

Client-Side Rendering (CSR)
- Pages rendered in the browser
- Best for highly interactive dashboards
- Set with: export const ssr = false;

Key considerations:
- SEO requirements favor SSR/SSG
- Real-time data needs SSR or CSR
- Static content benefits most from SSG
- You can mix strategies per route in the same app

Why the change?
- Better performance with optimized rendering
- Cleaner template syntax
- Built-in empty state handling with @empty
- No need to import CommonModule

Example:
Code:

@if (users.length > 0) {

    <p>{{ user.name }}</p>
  } @empty {
    <p>No users found.</p>
