Based on your search query, I believe Questionwell AI could be a great fit for your needs. This platform uses artificial intelligence to generate questions based on the material you provide, which can be text, images, audio, or video. This means you can input your OCR J277 Computer Science Unit 1 material, and Questionwell will generate retrieval questions for you.

Here are some key features that could be particularly useful:

• Question Generator: This feature allows you to generate questions based on your specific inputs. You can choose the topic, language, and question type (multiple choice, fill-in-the-blank, or short answer).
• Question Bank: This feature aligns the generated questions with essential questions and learning objectives extracted from your input text. You can also edit or add your learning objectives and standards.
• Export: This feature allows you to export the questions to various platforms such as Canvas, Quizziz, Quizlet, Kahoot, Blooket, Gimkit, Moodle, or Doc. You can also print the questions as a PDF.

Questionwell AI offers a user-friendly interface and different pricing plans, including a free Basic plan. However, please note that the Basic plan has limitations in terms of the number of questions that can be created and access to certain features. The Pro and Premium plans, which offer more features and allow for more questions, come with monthly subscription costs.
