Spelling Union
The Spelling Union of the S.Thomas College gives an opportunity for the college students to improve their Vocabulary skills and helps them to increase their creative thinking. Our main intention is to develop the student's vocabulary and writing skills throughout the game activities which are held in the general meetings. There will be an event announced each and every month to keep the members and the student's activity.Latest Project
