Sagacia marks your past papers and written answers the way an examiner would, estimates your grade, and explains your own mistakes step by step.
What you can do
Built with teachers and used in real classrooms, then opened to individual students.
Sit real past papers online. Objective questions are checked instantly; written answers are marked against the mark scheme, part by part.
Feedback follows the method, accuracy and reasoning marks examiners use, so you know which step cost you the mark, not just the final score.
Take a grade-estimate paper and get a predicted grade with a topic-by-topic breakdown of what to fix first.
For a question you got wrong, watch a short whiteboard walkthrough with voice-over that starts from your answer, then ask follow-up questions.
Pick a syllabus topic and difficulty and get fresh questions, marked the same way as the real papers.
Do the paper on paper, take a photo, and get it marked page by page.
How it works
