I have in the past successfully exported from a quiz (used both gift and xml), edited the questions in a text editor and then re-imported into a Lessons module. For True/False questions the correct answer should automatically score one point and move to next page, the wrong answer scores a zero and moves to same page. I use this type format for a question:
The radio popularized sports in the 1920’s.

The correct answer is not always placed in the correct answer box and it also does not give the score as 1, all answers are given a zero.
