NIMHANS is an excellent choice for those who are only interested in neurosurgery and are certain of pursuing a career in the same. However, you won’t be learning anything about general surgery. You’d do a craniotomy for EDH evacuation in a trice but will have a major problem putting your finger on an offending appendix.
Ultimately, if you are making this choice just because you want to pursue MCh directly, it’s better to reconsider your decision. 5-years is a long time to waste on something you aren’t sure of. So choose wisely after considering all options.
