Thumbnail script writing for a youtube video

I am starting a youtube channel for students of age 16-20 ,which are preparing for medical and engineering entrance examination after qhich they will get top colleges to do engineering and medical studies.I will earn money by providing subscription to my students.I will put a 5 minute pre sale video as my trailer video.This trailer video contains very little details about the program that i will offer,the video is more about understanding the need of my program and what i will do and not how i will do.I want you to write provoking script for the thumbnail of that trailer video.The script should be relevant to the content inside the trailer video as well as provokative in nature,so that they click on that.

Ideal candidates will have:
- Experience in scriptwriting, particularly for YouTube or educational content
- A deep understanding of the target age group
- Creative skills to craft a catchy, engaging thumbnail script.
