This paper presents an exam scripts marking system for answers written using pen and paper devices. Pen and paper devices capture the traces of pen movement (called digital ink), allowing the answers to be reorganized independent from paper format, analyzed and marked semi-automatically under the examiner's supervision. Based on our earlier work we designed a system which provides new features. The first new feature is to order answers based on the recognized content from the digital ink. While digital ink recognition is still not perfect at present, it will at the very least allow examiners to examine each similar group of answers at a time. Another feature introduced in the new system is the ability to overlay answers given as drawings such as graphs so that examiners can easily find the consensus answer as well as common mistakes. Yet another feature is to analyze the time that each student spent on a questions. This analysis is possible because in digital ink, each stroke carries a timestamp. The feature to automatically mark multiple choice questions in our earlier system continues to be available.
