1. Is this site enough to crack TCS or xyz exam?
Ans. No. These questions will give you a general idea of past questions and patterns given by TCS (or any company). You might get some questions as it is or same model questions with different numbers. Or you might not get any question at all. First you try to learn aptitude seriously in this site and follow the previous questions. But mugging up the answers may not help at all.
2. Is preparation or luck important to clear written test?
Ans. Success in aptitude = a × (Preparation) + b × (Luck) + c.
In the above equation the only variable in your control is "a". If your preparation is good, what ever be the remaining variables b and c, you can easily clear the written test. There are some lucky fellows whose "b" is high enough so that they get more questions from the previous papers. But not all of us are lucky. So if your preparation is good, you can clear at least some aptitude tests if not TCS. But If you depend on luck, nothing is in your control.
