How should I prepare with the aptitude for EY?

Hi Vibhav, thanks for your message. I would recommend checking out the EY Student Assessment Practice Hub (ey.preparationplus.com). This is a free to use platform created by EY to help you set yourself up for success throughout the application process. On this site you'll be able to learn about your values and learning style, understand your strengths, practice answering video questions and also take practice numerical tests. The more you practice, the better you'll become!

Would you suggest any other websites to practice aptitude?

Sure - I would say there's never such a thing as too much practice! You can find lots of practice websites via online searches.
