Hey Anupam !

Since you haven't studied in Class 11 but know about 60% of the Class 12 syllabus, the Leader Batch would be a better choice for you.

The Achiever Batch is usually for droppers who have already completed the full syllabus once. Since you have gaps in your Class 11 preparation, the Leader Batch will help you cover both Class 11 and 12 properly.

Since you are a little above average, with the right guidance and hard work, you can do well. Make sure to focus on Class 11 topics along with revision of Class 12.

Hope it helps !
