SQL server statemnt : I have created the following table:

CREATE TABLE Student
(
StudentID int PRIMARY KEY,
Name varchar(30),
Age int,
Course varchar(30), 
Year int,
Address varchar(50),
Phone varchar(12),
 Email varchar(50),
); 



**I was wondering how to run a query to show the year level and the number of students in each year level I need only to show year levels that have at least two students.**
