An incredible amount of time and effort is needed to develop high-quality video tutorials. Each video takes approximately 8-10 hours to complete which includes learning the concept myself, brainstorming creative ways to teach and explain the concepts, creating the presentations, video recording, and editing. Your support truly makes all the difference.
