One of our students was reading some of the messages from others about how scary a certain section of the course was. She convinced herself that if it was that hard for them, she wouldn't be able to do it. Finally, after delaying as long as possible, paralyzed by fear, she started working on it and found that it wasn't hard for her at all.
We're all different. What is difficult for one person may not be for another.
Don't let yourself be paralyzed by fear just because others say a section is very difficult. Talk to your instructor about it and get some guidance through the difficult parts. That's why they are there.
