Hey,
The most important points for choosing the best website for aptitude preparation are:
- Relevant practice questions
- Covers everything from basics
- Teaches you short tricks to score better
- Good doubt clearing sessions.
And PrepInsta checkmarks all of these points. Not to brag about the particular website. But when I was preparing for my placements, I just had a month to prepare and I was equally bad at logical and quants. My brother suggested that I visit PrepInsta and prepare from their study material.
