what is very though NEET or JEE

Well, a comparison between the difficulty level of NEET and JEE is like comparing the two sides of a coin. So, it is rather difficult. However, everything depends on your interests and capabilities.

The questions of NEET Biology are easy to level based on theory and a bit conceptual, the questions of NEET Physics and Chemistry are of moderate level. But the irony is selection is difficult in NEET due to increased competition as compared to JEE.

The questions of JEE Mains are of moderate to difficult level for each subject however, there is lesser competition and NEET.

But both has their significance so don't compare the difficulty level.
