Should the course be taken all at once? Can I save my progress and return back another day to continue where I left off to complete the course and get my certification?
Thanks for reaching out! As @wpolliard bestly put it, you can stop and go with the certification and take your time working through the lessons and exercises. However, there is a time limit on the exam portion of the certification.
You can stop and go as you please and HubSpot will save your progress automatically. If you learn best by taking each course all at once you can do that.
I have many certifications and have retaken many of the courses each year to keep my certifications up to date and find that spending an hour or two each night over the course of a week to complete the longer courses works well for me.
