Good luck

Yes its a decent book. If you have already bought it, then you can start solving it. It has good advance level questions that burst your analytical thinking and problem solving tactics and also boost your confidence. But at the same time, let me also inform you that DC PANDEY, HC VERMA and CENGAGE are the most used book by JEE Aspirants since they have lots of variety of questions from preliminary level to advance level.
