The exams are emphasized on understanding, applying and problem solving. The prof goes over things in lecture so quickly that it's really hard to keep up with him. His notes are also only in point forms so if you miss them at first try during lecture, then that's it. He gives a problem set but never posts answers, making us go over them in tutorials. Unfortunately my TA is unhelpful and going to prof office hours doesn't help either. I'm really stuck, especially with protein fusion questions...... The midterm is in less than a week and I still have lots of other things to memorize.. How can you crack this course? I'm so stressed out I think I'm gonna pass out.
 
Check out the textbook for the course, if there is one. If not, check the bookstore or library for related books. Seek out the other TAs for the course and your fellow classmates for help. Never assume that you are the only one having trouble.

There's a textbook for the course and the prof gives weekly assigned readings, all of which I do. But the prof covers additional topics and material not in the text. Even the material that overlaps in lecture and text differs. For example, while the text only briefly covers how protein fusion is made and lacks an example or sample question on how to solve it, the prof in lecture goes over a detailed method of making a protein fusion. As said previously, aside from his notes being in point form, they are also messy and don't make sense on their own. Obviously he wants students to take supplementary notes based on what he says in lecture, but his going over material too fast makes that really hard and almost impossible.
 
I had a cell & molecular professor who sounds very similar to yours, are you in Colorado?

Anyway, this was among my toughest recent classes, in reading the textbook my speed was something like 6 pages an hour to really understand the material, lots of pathways to learn that weren't intuitive to me at all. And in class, we'd go over technical lab processes in a way that made sense to a phd molecular biologist (the professor) but often I just scribbled as much as possible & tried to make sense of it later.

A thing to remember is that if you're having problems, others are too. I pulled through partially by really attacking different processes & areas important to our class.. dna library, transcription, translation, all the major areas. And I tried to memorize details about each major process that I could include in my essay questions on tests. This class covers some material I found pretty tough, just means that you may not be cut out to be a molecular biologist & will have to spend a ton more time studying.
 
Have you tried recording the lectures and listening to them later on?
 
Alberts' Molecular Biology of the Cell covers everything an upper-division undergraduate molecular biology course would. If you can read and fully understand parts II and III (of the fourth Ed. at least), it will be hard not to get an 'A' in your class. For me at least, the key to success in bio classes was to read the textbook.
 
I recorded every single lecture in college. How many of those recordings did I actually listen to? Maybe about <5% of them. However, for those tougher classes (or those with profs who had THICK accents), the recordings were truly invaluable

I keep up with assigned readings, but the text isn't very good.
It also lacks useful problems I can use to practice for exams.
Does the text by Alberts have lots of useful problems that can help you for exams?

You are obviously not understanding this material and you say the "TA is unhelpful" and "going to prof office hours doesn't help either". Why do these things not work for you? How can YOU make them work for you? Can you make an appointment with your professor to discuss getting what you need to understand the material and do well in the course?

No professor WANTS students to fail or do poorly in a course. You are paying tuition dollars and you need to get what will help you understand the material. Are you prepared for this course in terms of the prerecs? Are you making tactical errors on your problem sheets and quizzes? Your professor should be willing to go over your work so that you can learn from your mistakes.

If you can't get what you need to do well in this course, then you need to consult with the chair of the department and then with the dean. You need to request an appointment and take your concerns (in writing) to first the department chair and if no satisfaction, to the dean.

If you have the requisite background for this course, are diligently applying yourself in terms of putting in the study time and are attempting to get help from both the TA and the professor during office hours, then you have a case for something being irregular with this class assuming you haven't had difficulty with your coursework previously.

Another strategy is to try to get help from an upperclassman or someone who is doing well in the class who might be willing to study with you. Are there tutorial sessions at your school that you can take advantage of? In short, stop being worried and start being proactive about getting what you need to do well in the course. If you get "stuck" on something, move onto master something that you do understand and make a note of what you need help on for the professor's office hours/TA help sessions.

As for the lectures, purchase a small digital tape recorder and tape the class. If you miss something, you can go back and get the material from the tape. Also, be sure that you are not going to the class unprepared. This means that you have done your text reading BEFORE not after the class and you know what's in the text and what is not. Also, if you pre-read (don't read for memorization but for getting the gist of what is to come in the lecture), you have a better understanding of how the lecture will flow.

Just for your information, the MCAT emphasizes "understanding, applying and problem-solving" using the information that has been presented in your pre-med coursework. This professor may be doing you a huge favor by offering this type of examination experience so that you can do well on the MCAT.

I agree that this book is very good. A little outdated, since it was published in 2002, but it is loaded with really good information. It takes a while to read and digest because there's absolutely no fluff, but I just read it slowly and take notes in the margins.

No, the Alberts' book does not have any problems in it. There is a supplemental problems guide for the book though. I have it, and while the problems are interesting, and challenging, they are not the highest yield for doing well in the class. Amazon it; also the publishers website has some example chapters posted online that you can look at to get a feel if the writing style fits you. I'll say that this book is written like a novel. Like one of the posters above have said, this book takes time to digest, but it is written like a story or narrative.

To be honest, other than old practice exams, your best bet at imporving your biology problem solving skills is to go and work in a lab. If you are just not feeling bio and you know that this is not for you, then this advice won't do you much good. I came from an engineering background and found that I really enjoyed biology once I took an upper division bio class. Since then, I worked in a lab and after a year of molecular biology research experience, I had no trouble spitting out (correct) answers on biology exams or on the MCAT BS portion. For your course now, I would say that you should just REALLY try and fully understand everything you read. Often times, questions will be based on a figure in the book and you will have to describe what is going on.

They have a 5th edition now. I was even tempted to get it, but I figured that I would just wait until med school starts 😉.
 
Molecular Biology of the Gene by Watson et al. Best diagrams you could possibly find anywhere and text that is actually readable brought to you by the person who elucidated the structure of DNA.
 
i understand your frustration. this was the pre-req i found most challenging, especially since my bio background was weak beforehand. try not to focus on what the prof or TA is *not* bringing to the course, for it will only drag you down and provide excuses to fail. instead, you gotta assess your specific weaknesses, and then devise an attack plan that works best for you.

my plan: work with an amazing study partner with a learning style complementary to my own, talk through challenging concepts, record the lectures and make the time to listen to them prior to exams, and devise ridiculous memorization strategies for the processes/pathways/proteins. we used dominic o'brien's "quantum memory power" CDs to learn some memorization techniques, and my study partner went the extra mile by typing out our prof's lectures word-for-word when she replayed them because it helped her focus on the material. these became our lecture notes, from which we'd take individual notes for key concepts.

there's no substitute for time. if you're struggling, you'll need to put more time than usual into this class, and it's more painful if you hate the material. if you find yourself bitter about having to memorize so many tiny details, turn that frown upside down by reminding yourself how interesting and amazing it is that we can study biological processes on this level of detail. a positive approach can help you feel more enthusiastic about learning the material, even if you have to delude yourself into thinking it's the most exciting thing you've ever read.
 
Thanks for the posts, but... OMG I have my first midterm tomorrow and I'm not ready, especially for questions that ask you to devise experiments related to cDNA library, protein fusion, etc. Many techniques don't make sense and have so many procedures to memorize. OMG THIS COURSE IS SO MUCH HARDER THAN ORGO though I aced orgo.. OMG OMG.. OMG OMG OMG OMG I'm living in hell. 🙁 OMG.....

Starting now I'll use the Alberts text as supplement, try to preview before lectures and spend more time studying, as some of you advised. I have to ace this course no matter what.

Oh, I wonder why my school doesn't use the newer edition??? Maybe they want to save us some money...aw isn't that nice. 🙂

If you need it let me know after this semester 😉. Our professor recommended it but the readings don't parallel lecture very well. We've also been told that his lecture notes are a good preparation for the exam. I of course reference it when I need to.
 
stop beating yourself over the mindset of "i have to ace the course".

Just allocate the proper amount of time and do the best you can, prepare for the exams, and study each week. Stop freaking out about tests.
