Your teacher is likely confusing copyright protection with patent protection. Copyright registration is inexpensive, but is more than $20. Visit the Copyright Office website - www.copyright.gov for current fees and registration requirements. Patent protection is not available for a script idea. Visit the Patent Office website - www.uspto.gov - for more information about protection of inventions by patenting. GOOD LUCK!
