Soon we will upload All previous year's questions with answer of fluid mechanics and also all other civil engineering subjects ( Included GATE previous years questions + IES + State level Engineering exams + SSC JE + ISRO + RRB ETC )
All question with answer will be uploaded subject by subject , so that you all can analyze that , how many questions are asked by examiners in each paper. e.g. only 2-3 questions were asked in SSC JE 2015 by Fluid mechanics. So you can prepare for your examination according to that ..
