To understand the dos and don'ts of good GMAT prep, it's sometimes helpful to think about it like learning how to drive!

- In most countries before you learn to drive, you start with the theory alone (e.g. road code). In the GMAT it's best to spend the first phase focusing on theoretical foundations, before you throw in the additional difficulties like full GMAT questions and time pressure. Otherwise there's just too much handle at once.

- If you've never seen a highway interchange or roundabout before the driving exam, you're most likely to panic and freeze. For the same reason in the GMAT you want to experience the different types of questions you can get before the actual exam, by doing lots of practice questions.

- In fact in some countries by law you need to do a minimum amount of driving lessons (e.g. 20h) before taking the exam. There's no equivalent rule in the GMAT, but typically most improvements don't happen before a few hundred questions on each section. (see image).

- As you get closer to the test, good driving teachers will typically get you to practice in the most exam-like conditions (e.g. in the city centre with traffic if that's where you're likely to take the test). For the same reason in the GMAT you want to practice question in exam like conditions (e.g. in batches with a time limit). You woudn't approach a junction the same way with or without heavy traffic. For the same reason you wouldn't approach an algebra question in the same way if you have 1 min or 10 mins.

- Learning to drive with your parents makes you pick up some good habits but also a lot of bad habits. For the same reason you want to avoid preparing for the GMAT with sub-quality questions.

The analogy isn't perfect and I may have missed some points but just wanted to share the gist of it. Hope this helps!

Silly mistakes in calculations are close to universal among GMAT test-takers. Fifty years ago, students spent hours every day doing multi-step arithmetic by hand. Today people use calculators, excel or AI and our mental focus and stamina for extended arithmetic is much worse

Many test-takers blame themselves: "Math just isn't my thing" or "It's my ADHD". The reality is nowadays everyone has this tendency to some degree. The solution is to build a checking process rather than write off a category of errors as inevitable.

A common (and incorrect) image of a high GMAT scorer is someone who reads the question once, works through each step cleanly, and picks the right answer. In practice, strong performers re-read questions and double-check key steps. What may seem effortless is usually the output of a verification habit.

Yes, checking does cost time. But we can offset that from making educated guesses, estimations and choosing methods to avoid large calculations. Across a full Quant section, a robust checking process leads to far more correct answers than a faster but error-prone approach.

One more reason this matters: the GMAT's adaptive engine is particularly harsh on mistakes at lower difficulty levels. Getting an easy question wrong has a bigger downward effect on your score than missing a hard one.

But what's the best way to proof read a calculation? Don't try to check everything in parallel, but break it down into separate checks

Below is an example with some variables (x and y), signs and numbers. Not every GMAT calculation looks like this, but the principles can be used in other types of questions

Let's say we have the following

−2xy²(4x² − 5y² + 3xy)

Say in the next line in our notes we write down this:

−8x³y² − 10xy⁴ − 3xy³

Multiple errors are hiding in there. Can you spot them? Her'e a good way to proof-read**,** by focusing on one thing at a time

Signs pass (ignore all numbers and variables, only look at + or −):

• Term 1: negative × positive = negative ✓
• Term 2: negative × negative = positive, but we wrote negative ✗
• Term 3: negative × positive = negative ✓

Coefficients pass (ignore signs and variables, only look at the numbers):

• Term 1: 2 × 4 = 8 ✓
• Term 2: 2 × 5 = 10 ✓
• Term 3: 2 × 3 = 6, but we wrote 3 ✗

x exponents pass (same method) would also catch that Term 3 should have x² since x¹ × x¹ = x², but we wrote x¹. We could then do the same on y exponents (but there are no mistakes in that one!)

Corrected result:

−8x³y² + 10xy⁴ − 6x²y³

It may feel like it takes a long time to do, but the more you do it the faster you'll get. What takes time is jumping contexts between signs, numbers, exponents, etc. But doing one thing at a time effectively reduces that context switching and also reduces the likelihood of getting confused or mixing things up.

Hope this helps!

A lot of admits, especially career changers, get caught by surprise with recruitment during the MBA, and if you're not careful this can mess up the whole experience.

A few things many wish they knew before starting:

1/ Start before orientation
Recruitment windows are narrow and run in parallel. You usually have less than a few weeks before banking and consulting interviewing start. Arriving with a rough target beats arriving with a 'I'll have time to explore' attitude. If you want to go into banking start preparing now. If you're not sure what you want to do start ruling out some options now. Best way to do that? Talk to people in that job / career now. Message a few on Linkedin and ask for advice and a 5min call, in most cases someone will answer.

2/ If you're relying on career services to get you a job, forget about it
Not all MBA career services are great, but even the best ones are not going to be experts at all career paths. Usually they do a pretty decent job in banking and consulting since so many admits go into that, but for anything off the beaten track alumni are probably your best bet. Their main value is in transverse skills (CV feedback, mock behavioral style interviews (not technical interviews!), presentation coaching etc.). It's the same as in a company, you can't rely on HR to plan out your career for you, you have to do that yourself.

3/ The best way to explore a career is to work in it
If you're a career changer and want to use the MBA to explore, no amount of research or chats tells you as much as a few months on the job, so aim to do an internship or even several. I did three internships in my MBA!

4/ Most company presentations suck, so choose them wisely (edited)
There's a difference between networking and attending career presentations. There's a need for networking in certain careers, but that is more about quality than quality (doing your research and preparing opinions or good questions rather than just turning up to a presentation and say 'hi, I really like your firm'.
Career event FOMO is real, and it's expensive. Most career presentations you get far more attendees than reps from the company so you sit through 1h of presentation to get 3 mins of networking 10-1 (10 attendees per rep) at the end. If that's the company you really want then go to it, but my main point is that a lot of people just show up to all presentations without really planning things properly - better to go to a selected few and spend the extra time preparing). A lot of the firms where networking is important will organize separate events outside of the presentation (usually at their office or in a venue). Those are the ones that you need to get into and be prepared for.

5/ Those who don't get an offer within the first 6-12 months will start panicking
When many of your friends start getting offers and you don't - it's tough for multiple reasons. Your ego takes a hit, you start worrying about the RoI of the whole MBA, but also you cant relax and do all the other MBA stuff your friends now have more time to do. Be prepared for this because it can happen to all admits. Keep your focus and stick to your priorities, whatever they are. For some career paths it's normal to not get an offer until late into the program.

One year out of a top MBA program, many graduates will privately admit they're not fully satisfied with their first role. This doesn’t mean they should not have done an MBA, it's just how the career path tends to work, and if you're considering an MBA it's worth understanding why.

Most MBA roles are designed to bring in flexible, versatile talent rather than leverage your specific background.
Why? Because if they wanted a specific background (e.g. retail), they would not recruit from an MBA since each class will only be a small percent with that background. So they have to design the MBA role to be a generalist one rather than a specialized one.

That means in your first job you'll likely do a bit of everything, and your pre-MBA skills will be "nice to haves" rather than core requirements. (e.g. they wont care in most cases). This is fine if you wanted to leave your pre-MBA world forever, but you may still find it frustrating that you don’t your opinion doesn’t count as much as it did before, when your role happens to touch on things you do know about.

The 2nd role is where things really open up.
Corporate strategy teams, business development, mid-level PE, specialized consultancy roles, etc. These positions value both your MBA skills AND your experience (usually your post-MBA experience, but sometimes also your pre-MBA experience). The hours tend to also get a bit better (or at least your effective hourly rate)

So why don't more people switch earlier?
Mostly practical stuff: loans to pay back, sign-on bonus clawbacks, and the sheer difficulty of job hunting while working long hours. It's a real constraint, but knowing it exists helps you plan around it from day one.

Anyone else experience this arc? Would love to hear from people who took the ops or entrepreneurial route too — seems like a very different journey.

The first role is a stepping stone, and the best thing you can do is treat it as one. In retrospect I see my 2 years of MBA + 2 years of consulting as 4 years of career transition.

Congrats on those who have been admitted! Most people treat this window as dead time, but here are some tips on how to make the most of it:

Take some time off . MBA life can be intense. Arriving rested is worth more than squeezing out a few extra paychecks before school starts.

Invest in your relationships. The MBA will strain them. so use this period to spend real time with the people who matter most to you.

Get clear on your priorities before you arrive. FOMO is real. Every day involves trade-offs between clubs, recruiting, academics, and socializing. The clearer you are going in, the easier those calls become.

Find housing early. Good MBA apartments get passed between cohorts. Arrive late and you'll scramble. Arrive early and you'll likely inherit somewhere well-optimized, with tips from the previous tenant.

If you're targeting a finance job, start preparing now. Recruiting hits you hard when you've just arrived, and if you wait you'll have a disadvantage compared to those who have done more reading on deals, thought about their investment theses, and networked with target firms. It's less important for consulting and corporates.

Handle admin before things get busy. Direct debits, cleaner, food/shopping delivery etc. Set it up now. You won't have time for much life admin during the course.

Do some pre-reading if you're not from a finance or analytics background. Stats and finance come up fast. A bit of prep buys you time for higher priorities later.

Consider traveling before school. Organized trips happen during the MBA, but they don't leave much downtime. A pre-term solo trip is good way to spend time thinking about what you want to get out of the next few years.

Show up to the pre-term socials. Social circles form fast once class starts. The pre-term window is your best shot to meet people outside your eventual study group or club.

Make the most of it. It will most likely be one of the best periods in your life!

Happy to answer questions from anyone starting this fall.
