Formula for multi-cell status update

Hi all - First Discussion here. I am trying to use a formula that will populate a cell with "Not Started", "In Progress" or "Completed" based on the condition of eight cells in the same row have data in them or not.I have created two formulas that work in part but cannot figure out how to properly combine them.The idea is to have the cell show "Not started" when all eight cells are blank, "In Progress" when any of the eight cells are not blank, and show "Completed" when all eight cells are not blank. Any Suggestions?

This formula shows "Completed" only when all eight cells have data, otherwise it shows "In Progress"

=IF(OR(ISBLANK(INST3), ISBLANK(ASGN3), ISBLANK(TEST3), ISBLANK(CODE3), ISBLANK(ALRM3), ISBLANK(GRPH3), ISBLANK(TREND3), ISBLANK(TUNE3)), "In Progress", "Completed")

This formula shows "In Progress" when any of the eight cells have data, or "Not Started" when all cells are blank

=IF(AND(ISBLANK(INST3), ISBLANK(ASGN3), ISBLANK(TEST3), ISBLANK(CODE3), ISBLANK(ALRM3), ISBLANK(GRPH3), ISBLANK(TREND3), ISBLANK(TUNE3)), "Not Started", "In Progress")
