which place I should go in North-east in india after 10 to complete ias course

Hello,

First of all in order to appear for UPSC, candidates need to pass graduation in any discipline from a recognized board, there is no specific aggregate required in this case, you need to be 21 years old and can appear even in the final year of graduation, now you're only in 10th and there is long way to go before completing graduation, as I told there is no such barrier of belonging to any specific stream when it comes to appearing for UPSC, and regarding coaching classes there are many, in fact some of the top coaching classes also offers courses related to UPSC Civil Service Exam in online mode, there might be colleges which offer preparation help regarding this civil service exam, but there is no such college which offers IAS degree, because to qualify IAS you need to be in top merit list of UPSC, and if you belong to UR then within 100, so that's a long process ahead, but if you're wholly and solely focused on this career, it helps if you belong to humanities stream as UPSC exam is more humanities oriented in terms of the content of the subject, other than this if you wish to pursue other professional or general degree, that also fine, many people from diverse background qualify this exam, and you too can surely.
