Why HIJACK BIGDATA?
English teachers manually create dozens of question types for every exam: line-by-line translation, grammar, blanks, ordering, insertion and written responses from the same passage. Preparing them and adjusting print layouts can take hours of work.
HIJACK BIGDATA automates that work. Register a passage once to print the worksheet types you need, or use AI to generate new questions in seconds. Automatic A4 layouts let you print without extra editing.
