Skarp allows you to learn anything for free in 20+ languages. Our course creation engine combines automation, human experts and recurring content quality audits to create in-depth courses on any topic of your choosing. We focus on depth, not summaries. For each course you get: - A syllabus - Lectures (audio and visual). One lecture is roughly 15 mins, and a course can have on average 10-15 lectures. - Study textbook - Practice exams for each lecture to make sure you understood the topic - A certification exam that tests the whole course and grants you a certificate of proficiency on passing FREE PUBLIC COURSES You can create courses for free through the app. A waiting list will automatically be created for your course, and course creation is prioritized based on the number of people on the waiting list. Inviting friends to sign up can mean same day creation. WHAT COSTS MONEY You need a subscription if you want to create more than one private course per month, want more than one Skarp certification, or want to use our study loop feature to for example prepare for your professional certification exams. THE STUDY LOOP HELPS YOU MASTER ANY TOPIC The study loop works as follows: - Take a free diagnostic against the formal certification to see what you know and what you need to learn - Study the materials for the course that are adapted to your knowledge and take the exam - Get a study guide built from your wrong answers, helping you deepen on your understanding on the topic you find challenging - Take a new exam and get a new study guide based on your latest results - Repeat until you master the topic CERTIFICATION PREP Skarp is particularly well suited for certification prep. We have created a unique human-audited adaptation of our study loop engine that helps you prep for certifications such as ITIL 4 and ITIL v5, AWS Cloud Practitioner and Solutions Architect, CompTIA Security+, Cisco CCNA, Azure AZ-900, Google Cloud ACE, PMI CAPM, Scrum PSM I and FINRA SIE with thousands of questions independently cross-checked for correctness and against the official exam blueprint.
