How do people actually finish TTP? I've been studying for months and still feel far from done

I purchased the 4-month TTP course, but even after studying for most of the day for months, I'm still struggling to complete it.

I feel like I'm spending a lot of time learning the material, but my progress through the course is much slower than expected. I'm wondering if my note-taking and revision strategy is the issue.

For those who completed TTP:

1. How long did it take you to complete TTP, and roughly how many hours per day were you studying?

2. Do you take notes while going through TTP? I tend to write a lot because it helps me learn and retain information, but I suspect it's also slowing me down. How did you balance note-taking with making progress through the course?

3. For those who have completed TTP, would you recommend the calendar-based study plan or the mission-based study plan? Which one helped you move through the material more efficiently while still retaining what you learned?

Thanks for helping.
