About Eval2Sharpen Education
The consistently high cost of private tuition, and limitations of manual marking inspired us to develop Eval2Sharpen Education. Affordable, quick and comprehensive, it allows students to understand and learn the gaps and points for improvement in their essays, while parents and teachers can be part of the learning process by easily tracking their progress.
