About the work

• We give you the syllabus below and a sample notes PDF to record from. The notes unlock once you fill in your details in the form.
• You send back a link to an unlisted YouTube video or a Drive video of yourself teaching from those notes. Nothing to upload here.
• Selected educators have 3-4 weeks to submit the full recording.
• Payment for the subject: Upto 1500-2000 (Based on Hrs of recording).
• Shortlisted applicants are contacted by our team with the next steps.
