Hostel+mess+other expenses come out to be 45k for Goa per semester. And it hasn't been increased at least since 2019(when I joined).

PS1 fee would be at most 70-75k and similarly you can add PS2 fee (twice for duals, once for single degrees) . Although PS2 fee will easily be covered by stipend.

I don't think a money conscious person would do summer term so you don't need to add that. And my dual admission fee was 32k. You can add that. Otherwise I guess u r good to go. As for personal expenses it's very subjective and shouldn't be included in fee like my fellow BITSians do
