How can I have separate classes for Reading, Writing, Spelling, etc. but still have ONE Language Arts grade?

Grade book categories will not transfer to the Report Cards.  So you can have your grade book setup with whatever weights you desire, and it will not carry into the Report Card.  The Skill grades are entered in Manually (once per grading period) because those are completely different marking codes, as required by the NAD. Although the desired categories in Language Arts reflect the skills in that subject as printed on the report card, the averages of those categories only add into the overall subject grade and do not individually carry into the Report Card.
