Following are some of the pretty good sites that provide quality aptitude questions for various placements:
- Indiabix – My personal favourite. I sat for the campus placements of Wipro and Capgemini. Wipro included AMCAT test pattern. And believe me 20 out of 25 questions in quants were what I already did in Indiabix! Capgemini follows COCUBES. Here more than 50% section of both quants and logical were from Indiabix!
- m4maths – Another great website that provides separate questions for every company you are going for!
- Lofoya – Similar to Indiabix.
- Freshersworld – One of the most trusted websites for every Btech student 😉 Actually it’s a very awesome website that has a library of more than enough questions on any topic, but the only problem is the flood of typo errors in the answers they provide.
The above are some very good sites that provide decent online learning material. But I would personally recommend you to buy a hard copy preferably “RS Aggrawal QUANTITATIVE APTITUDE”.
