The course was taken in Summer, so the Business Strategy section is not covered. If you take this course during Fall/Spring, this section is probably included. The main professor for the course (and the one that covers Business Strategy) passed away the first week of the Summer session (he was the best thing about this class).
The Head TA "took over" in his absence, and seemed over his head. His responses were rude most times, condescending others, and seemingly tired of hearing the same questions over and over. That being said, a lot of the questions students were asking were covered a thousand times, and make one wonder if they were even capable of brushing their own teeth.
Your mileage may vary going forward.
tl;dr
Attend the live sessions
Watch the async videos
Attend the TA office hours for Accounting and Finance
Memorize "everything"
Long version:
The class is broken down into several sections, each taught by a different professor:
Financial Accounting
Finance
Supply Chain
Marketing
Business Strategy
Half of your grade in the course will come from the first two tests. These are closed book, closed note, closed internet, closed everything and rely heavily on memorization. Accounting and Finance consist of roughly half "theory" questions and half "problems." The problems are mostly straight forward if you do the practice problems and GO TO THE OFFICE HOURS. The TA's that offer the hours for these two sessions are amazing and go through in great detail.
Get used to creating the formulas in Excel. They do provide a formula sheet, so you do not have to memorize these. But seriously, do the problems several times from scratch. You're going to have to create a Balance Sheet and Income Statement. There's a great chance the Balance Sheet will not Balance on the test. They did this intentionally to make you realize it has to balance, and thus, you had to add the missing value in. My advice? Check the answers given for subsequent questions, backtrack from there, and you'll find the missing item (assuming they use the same problems, which...it sounds like they do).
There are also questions that come up saving "What % returns such and such?" Why bother calculating it when they give you the %s in the multiple choice? Throw those into your formula, get the answer that matches, and there you go. It's basic algebra but they don't ever explain that. Instead they want you to struggle/go through the hard way. Don't play their game. Always look at the answers first, as most times, you can just plug them into the easier formula and get the answer. There's also only four answers, so we're talking seconds to do this.
For the "theory" portion you'll have mostly True/False, Fill in the Blank, Statement 1/Statement 2 are True/False/Both/Neither. There isn't much you can do here but memorize. If you ask the TAs what you memorize, they'll tell you everything. I can't help you here, focus on the problems since those are methodical while making flashcards for nearly every topic covered in the videos. Both videos. The async and the live office hours.
Ok, that gets you through Accounting and Finance. Hopefully you're sitting rather pretty here, because unlike Professor Fury (RIP), the Head TA will not be doing you any favors. He did not curve any grades (despite Fury always curving). He did not give any feedback (despite Fury being amazing at it). He did accuse the entire class of cheating though, so hey. There is that.
Next comes Supply Chain and your first "Homework" assignment. This is part of the ~$60 Harvard Course Pack (yes, you need this, some of the case studies are on the tests, and you need the simulations). You're given three chances to do the simulation. RECORD EVERYTHING YOU DO. Write it in Excel, on a napkin, take pictures, but every step, record it. The reason being, nothing changes in subsequent tries. Meaning, you know exactly what will happen and what happens based off what you do. The "Board Members" will also ask you questions about why you did such and such. If you have no clue, pick an answer. Write it down. You'll know if it's right or wrong the next time around and can adjust what you answer.
Take your first attempt and make some educated guesses. See what happens. Write down the answers. Consider where/how to improve. Also consider you know the EXACT demand of the phone based off what you selected. You could possibly PRODUCE the exact number in your next run through...
Take your next two shots here to do well. You're aiming for a high profit and high board votes. You should be able to get at least an 80% on this with simply tweaking what you did.
Next is the Supply Chain test. It's more theory than problems, but does have some problems (far easier than the previous two sections). You should be ok here as Supply Chain is relatively straightforward, but don't take it for granted. Put the time in to memorize and go over the problems. For entertainment, you can create a game of the number of times the professor says "right" in the recorded and live videos.
Finally (for Summer) comes Marketing. There's something extremely off-putting about the professor for this, and none of that is helped by his topic being the worst, most irrelevant, and boring covered in this class. You also have another simulation. However, they give you unlimited tries for a week or so period before resetting it, and having you submit your "real" run through. You have no excuse not to get an A on this using the same process as Supply Chain, except now it's unlimited tries. Run through it until you make all the perfect decisions for your choice WRITE THEM DOWN, and come the "real" turn in, just do that exact run through again.
As for the test? It's 100% pure memorization of garbage. There are no problems. No ways to apply the "knowledge". Nothing. It's 40-some questions of Marketing theory, True/False, Statement1/Statement2, etc etc etc. This is the test the Head TA and professor accused the class of cheating on due to several(?) finishing the test within 10 minutes. Honestly? You either know this crap or you don't, so 10 minutes is probably too long anyway.
If you're taking this in Fall/Spring, Business Strategy falls in there somewhere. But with Professor Fury gone, I imagine they'll tweak it to have someone else do the live videos or do away with them entirely.
I highly suggest taking this class in the Summer for nothing else to be done with it so much quicker. Note, if you do, your first test OPENS the second week of class and is DUE early the third week. It's a rocket-speed pace through these topics, but once one is done, that's it. There is no cumulative final or midterm. Each module is self-contained. Once done, it's done. Take a shower and move on with your life.
You'll never use the material taught in this class. Some topics are interesting (mostly finance due to the stocks and how some aspects work), but at least half the class is worthless, with a third of it already being covered (by the same professor no less) in other required courses. The best thing I took away from this class was the knowledge that GT offers all students a free subscription to the Wall Street Journal.
Good luck. May the odds be ever in your favor.
