Hello Nikita
Check this code
[HttpPost]
       public ActionResult Create(Student s)
       {
           if (ModelState.IsValid == true)
           {
               db.Students.Add(s);
               int a = db.SaveChanges();
               if (a > 0)
               {
                   //ViewBag.InsertMessage = "";
                   TempData["InsertMessage"] = "";
                   return RedirectToAction("Index");
               }
               else
               {
                   ViewBag.InsertMessage = "";
                   return View();
               }
           }
           return View();
       }

There are two returns that return a View or a redirect. There has to be another return at the end of your method returning a view or redirect.
