Hello Sneha,
According to what I found, currently, for 2018, the number of available seats in the Geology Science course is around 43.
The aggregate required for Geology Science is the sum of your 12th board marks in Physics, Chemistry, and Maths (out of 100 each). If you belong to general category 275/300 should assure a seat in geology course in JU.
Hope this helps. You can contact for any further guidelines.
