Grading multiple choice and cloze questions created with exams2moodle()

I am using `exams2moodle()` from R/exams to create multiple choice and cloze questions in Moodle. Before preparing exams, I would like to be certain how Moodle computes grades. It seems to me that in multiple choice questions the default setting in the evaluation policy is `partial = TRUE, rule = "false", negative = FALSE`. Is that correct? For the cloze questions, it seems that the overall grade assigned to the cloze question is divided equally among the subquestions. I wonder if there is some way to give unequal weight to the single sub-questions. Thank you in advance for any help!
