Is General Chemistry Hard?

Hello everyone, I'm a mechanical engineer major and I'll be taking the first semester of the general chemistry sequence at a university this upcoming semester. This is the only chemistry class that I need. I transferred from a community college to CSU Long Beach and I'm done with the math, the first semester of calculus based physics, and the general ed requirements along with some engineering courses. I took an introductory chemistry class in 2007(college), which is the prerequisite for the general chemistry class, and did well in the class. It's been a while since I've seen any chemistry because I've been working full-time and gave priority to other things until now. I was just wondering, how much information overlaps between the two courses? Is this course hard relative to an introductory chemistry class? I'm not sure if it is a good idea to take this class without being fresh from chem. I'm not sure if this class reviews a lot of the basics before starting new information or if it jumps straight into new concepts and I'm expected to know electron configuration, the periodic table, molarity, etc. If the class is very similar to the introductory course offered in college, then it should not be a big deal for me. I was hoping someone could give me an insight by sharing similar experience. I'm going to try to review for the class, but I'm currently taking summer courses. If I can get away without reviewing and still be in a position to do well in the class then I'll just do that. For some reason, the department of chemistry likes to scare students who didn't take the intro right before taking general chemistry. By the way, the professor teaching the class has good reviews by other students.
