In a unit test, do you verify and assert?

I am using Moq in my unit test project. Most unit test examples I've seen online end with someMock.VerifyAll(); I wonder if it is OK to assert after VerifyAll(). So for example,

//Arrange
var student = new Student{Id = 0, Name="John Doe", IsRegistered = false};
var studentRepository = new Mock<IStudentRepository>();
var studentService= new StudentService(studentRepository.Object);

//Act
studentService.Register(student);  //<-- student.IsRegistered = true now.

//Verify and assert
studentRepository.VerifyAll();
Assert.IsTrue(student.IsRegistered);

Any thought? Thank you.
