📌 What is TCS IPA?

IPA (Incentive Pay for Associates) is a performance-based exam conducted by TCS for its associates. It consists of multiple sections that test both technical and professional skills:

Section	Marks	Topics
Java Coding — 35 Marks	35	OOP class design, static methods, array of objects
Java Coding — 15 Marks	15	String/number manipulation programs
Java MCQ	varies	Core Java concepts, output prediction
SQL / PL-SQL	varies	Queries, joins, subqueries, cursors
Unix / Linux	varies	Shell commands, file permissions, processes
UI (HTML, CSS, JS)	varies	Web fundamentals, DOM, events
KYT (Know Your TCS)	varies	TCS history, values, Business 4.0, MFDM
BizSkills	varies	Communication, workplace ethics, 7 C's

The 35-mark Java question is always an OOP problem. Cracking the universal skeleton for it is the single highest-leverage thing you can do.

🎯 IPA Question Bank — IPA-Questions/

All real TCS IPA exam problems are consolidated in one folder — no more hunting through the root.

Every sub-folder contains:

• .txt — the original problem statement exactly as it appears in the exam
• .java — a clean, working solution

Range	Topics Covered
IPA1 – IPA10	Course/Employee class design, sorting, filtering, second highest
IPA11 – IPA20	Book, Player, Product, Footwear class problems
IPA21 – IPA30	Travel, Hotel, Medicine, Vehicle problems
IPA31 – IPA40	Mixed OOP problems with string + number methods
IPA41 – IPA55	Advanced scenarios, combined logic, edge cases
2nd_Lowest_Salary	SQL-style second highest salary via Java
Company_Employee	Employee filtering + sorting patterns

💡 Tip: Before looking at the solution, try coding it yourself. The .txt file has the full problem statement and sample I/O.

🗓️ Day-Wise Study Plan (Day 1 – Day 29)

The Day X folders mirror a real 29-day structured study plan. Each day folder contains:

• Concept Java programs practiced that day
• IPA questions attempted that day (sub-folders like IPA 2, IPA 5, etc.)

This gives you a roadmap of how to pace your preparation if you're starting fresh.

---

📅 Suggested Study Schedule

Day	Focus
Day 1–3	Java basics: I/O, conditions, loops, functions
Day 4–5	OOP: classes, objects, inheritance
Day 6–10	String manipulation patterns (most common IPA topic)
Day 11–15	Number/math problems, prime, fibonacci
Day 16–20	Advanced strings: HashMap, sliding window, sets
Day 21–25	IPA practice: attempt 35-mark questions from scratch
Day 26–27	SQL + Unix crash course
Day 28	KYT + BizSkills + UI revision
Day 29	Full mock: 2-hour timed practice session

🏆 Top Tips for Each Section

Java (35 Marks)

• The class structure is always the same — learn the skeleton once
• Always write getters, setters, AND constructor even if not explicitly asked
• Method 1 usually filters/counts; Method 2 usually sorts or finds an extreme value
• Output messages must match exactly (copy from the problem statement)

Java (15 Marks)

• Focus on: reverse, palindrome, vowel count, prime check, fibonacci, Armstrong
• Keep a isVowel() helper method ready — it's reused in many problems

SQL

• Know GROUP BY + HAVING cold — appears in nearly every paper
• Practice correlated subqueries and NOT IN / NOT EXISTS patterns

Unix

• chmod numeric scheme (r=4, w=2, x=1) — always tested
• Know ps aux, grep -i, kill -9, and pipe | usage

KYT / BizSkills

• MCQ traps: "Teamwork" is NOT a TCS core value; "Confident" is NOT one of the 7 C's
• If you don't know an answer in a client meeting → acknowledge + follow up (never bluff)
