Hi Aspirant!

To be eligible for NEET candidate must have atleast 50% in 10+2 with the required subjects from a recognized board and same is for admission in AIIMS. And this includes the total marks (theory and practical both). So, as you mentioned that your exam is of total 150 marks and lets assume that you achieved 130 marks out of total, then the percentage of it is (130/150)*100= 86.6

So, in this way you can calculate your percentage and check if you can write NEET exam or not.

Hope I answered your query, thankyou!
