Classic Sudoku (Fun With Sudoku #20)

A few years back I was part of the Toastmasters International club named Bangalore Toastmasters Club. I have completed my Competent Leadership program under Toastmasters. This is the second Sudoku that I created for the Bangalore Toastmasters Club newsletter. The hint given reads BTM (Bangalore ToastMasters). I miss Toastmasters a lot and hopefully soon, I will be again a member of Toastmasters.

I am re-publishing this Sudoku as 20th Sudoku in the Fun With Sudoku Series. Can you solve this Classic Sudoku puzzle?
