I was searching for a question bank when I came across this test book app.
I downloaded and went through the question bank for JEE entrance exam but when I went through some hundred questions I realised that it is not matching the level of JEE MAINS EXAM but it it was just the level of NEET and also it only included the topics which were more focused and based on the NEET exam.
It really sucked my mind as I had already paid for it.
So anyone whom is preparing for JEE entrance exam I would recommend go for a better question bank than this.
