(How much) can I improve my score?

You should set your expectations that you will require a LOT of effort to get up there.
I hope you will be the greatest improvement student on GMAT Club with 370 points of improvement. However, right now the record stays at 300-310. I don't mean to say you can't reach that goal... all I am saying is that no one else has so far.

From what I have seen, a person can achieve GMAT score increases as long as she or he keeps going, uses effective approaches, and keeps finding new levers to pull.

We often hear that people's GMAT scores top out at certain levels, but to understand what's going on, we have to examine those stories thoroughly and ask ourselves whether those people kept going, used effective approaches, and kept finding new levers to pull.

Many people believe in score ceilings or don't really care to achieve large score increases. So, simply looking at what happened without considering why it happened is not particularly useful. Sure, someone achieved a score increase of under 100 points and didn't achieve any increase from her or his second to third GMAT, but what did that person do, or not do, when preparing?

On a related note, the current GMAT Club score increase record, and what is quite possibly the largest GMAT score increase ever, was achieved by member daldilaimi, who achieved a 530 point score increase, going from her first GMAT score of 250 to her final GMAT score of 780.

Marty - thank you. That's a nice reply but the OP has already graduated back in 2015

Would love to use your firepower perhaps in another topic and by the way, great YouTube Live on Friday!

People are still coming to this post for information on what constitutes a reasonable GMAT score increase. Hence the over 23K views. So, I put in my 2c and updated the record.

Continuing the general thread on how much of a score jump is possible on the GMAT.

It all comes down to the WHY question. Why did you get your most recent score on the GMAT?

The OP was right to focus on the nature of the GMAT -- it's NOT a Math or English test (a knowledge test as he called it). Once you've understood that it's a test of Executive Reasoning -- then you can focus properly on assessing your gaps to being ready to hit your target score.

The key thing to remember is we've all had very different education and experience that has shaped our reasoning skills. But they can be learned with very focused effort and ideally great coaching.

Based on client experiences (1100+), I can refer to the following timelines:

Jumps of 200+ points in 3-4 months
Jumps of 100+ points in 2 months
Jumps of 30 to 50 points (depending on starting score) within a month.

The key is focus -- if you can answer the WHY question (what were your gaps that caused you to get questions wrong) -- then you can focus your efforts more closely and get to your target much faster.

There are 2 reasons why improving your GMAT score takes so long on your own:

1) You don't know what your really gaps are (WHY question again) -- so you do a lot of unnecessary work with a 25% or less of really effective effort -- that means out of every 20 hours less than 5 hours is actually helping you to improve your score.

2) Lack of expert help. You can't see your own process gaps because you don't have the experience in coaching so you self-coaching becomes a two step process. 1) learning to be your own coach then 2) actually coaching yourself through the required improvements.

Happy to get on a call with anyone who needs help creating focus in the RETAKE prep -- and even doing a FREE diagnostic session if it makes sense.
