Stop grinding random DSA.
Start practicing the actual OA format.
TCS NQT, Infosys, Wipro — they don't just ask LeetCode. You get English, Reasoning, Quant, CS Fundamentals, and Coding, all in one timed session. MockOA simulates that exact pattern so there are no surprises on test day.
Free. No credit card. Just your Google account.
> INITIALIZING SIMULATION...
> PATTERN: TCS NQT-STYLE OA
> TOTAL SECTIONS: 5 SECTIONS
> MAXIMUM SCORE: 125 MARKS
> TIME LIMIT: 120 MINUTES
Witness a simulated mock OA attempt. We will answer English, Reasoning, Quant, and CS MCQ questions, compile Python code for a Coding problem, execute sandbox test cases, and analyze the score.
Not just coding. The real OA has English, Reasoning, Quant, CS Fundamentals, and Coding — each timed, each scored separately. You need to be good at all five, not just one.
Your code runs in an isolated sandbox — C, C++, Python, Java, whatever the real OA supports. Same timeouts, same constraints. No cheating with local IDE shortcuts.
You don't just get a score. You get a breakdown of what went wrong, which topics to revise, and where you're losing the most marks. Like a study partner who actually took the test.
The Pattern
Modeled on the TCS NQT-Style OA — 125 marks, 5 sections, 83 questions. Every mock you take follows this exact breakdown.
English
Reasoning
Quant
CS Fundamentals
Coding
You've seen the pattern. Now practice it.
One mock takes about 2 hours. That's less time than you'd spend picking which DSA sheet to follow. And this one actually maps to the test you're preparing for.
