Hundred Miles is a small but focused leadership initiative that works with young people from rural and semi-urban areas who want to learn, earn, and grow but lack the resources and motivation to do so. The project recognises that skill development alone is not enough when daily economic pressure and social barriers shape people’s choices. By combining basic financial support, practical skill training, and pathways to earning, Hundred Miles attempts to create motivation from within. It is a slow and grounded effort to help first-generation learners build confidence, dignity, and enthusiasm—both for their own growth and for the students they teach in their communities.

The 12th week of the Sundarban Faculty Training Programme combined evaluation and skill development through an English assessment, digital training, and communicative practice. Participants completed a structured question paper to reflect on their learning progress, followed by an introduction to Google Sheets for practical skill enhancement. The session concluded with a communicative English class that helped build confidence and reduce hesitation, making the week both reflective and forward-looking in supporting continuous growth.
The 11th week of the Sundarban Faculty Training Programme focused on reinforcing core English skills through a balanced approach to grammar, writing, and speaking. A revision of be-verbs helped clear lingering doubts and strengthened participants’ grammatical foundation. This was followed by practical training in official email writing, where participants learned to communicate clearly and professionally in formal contexts. The session concluded with a three-minute speaking activity on Sundarban, which encouraged participants to practise spoken English and build confidence. Overall, the programme effectively enhanced both communication skills and self-assurance among the faculty members.
In Week 10, teachers strengthened their understanding of English grammar, learning Subject-Verb-Object and be-verbs while continuing tense practice. They also developed digital communication skills by practicing how to write clear and professional official emails.
