Yes. Put down as much as you can even if you are faced with a calculation and you feel it is incorrect. The more work you show and the more you explain what you are attempting to do, the better. I know for a fact one of my calcs for my Essay question in part 2 was incorrect but I did a decent job at explaining.
Since you're taking part 2, definitely commit to memory that IMA Statement of Ethics, knowing the all line items associated with the principles and standards. No test is the same, but ethics definitely was one of my essay questions.
Overall you seem to be in a good place, if your only struggle is Ch. 6 with well over a month left and you are scoring 80% or higher on Gleim MCQ, you should be fine! I would take a least 2 practice test between now and your exam date to make sure you are managing your time correctly.
Good Luck!
