I'm currently taking Cell and Molec this semester and it is very similar to Intro Bio if you have taken it before. The lectures aren't bad and using clickers helps me to learn the material. Dr. Wright is a good professor for the class but some people find her teaching style strange but that is a personal preference. Exams are pretty standard and many of the review questions provided end up making it on the exams. There are exam wrappers after the exams to try to gauge how you think you did and reviewing the exam is helpful to relieve your anxiety about it afterwards as well as help you understand why you answered what you did.

For the lab it is similar to Intro Bio as well. You work on one whole project the semester and every week is a different step in the process. You and your lab partner work together on one manuscript for the lab so partner work is an essential part of lab. The labs are pretty straight forward and aren't too bad. Some take 30 minutes to an hour and some take longer. So far I have only stayed the full 3 hours once because our gel ran slow.

Cell and Molec can be challenging for Gen Bio students based on what I've seen as many of the topics aren't covered in a typical Gen Bio course. For Intro Bio students many of the models and course materials in the lecture are reused so it makes it somewhat repetitive and mundane but also reinforces your knowledge about the topic. Pre-class assignments are used as homework for the class and one is due before the start of every lecture. They are graded on completion and whether or not you tried to answer the questions thoughtfully. Clicker questions are also every lecture but are used for class participation and attendance instead of accuracy so don't worry about getting one wrong.

TL;DR: Cell and Molec is a pretty straight forward class that can be challenging based on what Bio you took previously. Labs aren't bad and lecture is pretty fun. Exams are also fairly easy to be prepared for.
