Relationship between SAT and GMAT score?

Yes people who do well in the GMAT also tend to have done well on SAT since both follow a similar standardized thinking pattern

You need more self-confidence man. No excuses. Study and do well on the test.

Only took the two section SAT but I made a 1220, no idea the spread. I made a 690 on the GMAT. SAT is more like GRE. GMAT is much different IMO

Good Day:

Ah yes, I remember it well: Sweating bullets over midterms while prepping for the GMAT so that I can enroll for the Fall Semester in my graduate school of choice.  In short, I had a 710 GMAT, 98th percentile over 72nd percentile score on the ACT.  Take every chance you can to study the segments of the test and then go out and knockout the competition.  Break up your study materials into What you have down cold, what you have down, but not cold and that which you need the most work on.  Spend two thirds of your time on that which you do not have down cold and one third on that which you need the most work on.  Next step: Find the best tutor you can.

Good Luck

2310 (1520) SAT/740 GMAT

2310 SAT 

760 GMAT

33 ACT / 740 GMAT

Looking back at my SAT, I scored in like the 60th percentile (I didn't take it seriously and didn't study). Flash forward to GMAT and I scored in the 90th percentile (700+). Personally, I don't think that your level of success on the SAT necessarily predicts your level of success on the GMAT, but, if you are in that kind of situation, I think that you would need to be a substantially different person in terms of work ethic and dedication in order to outperform on the GMAT. 

With time, effort, and a bit of luck you definitely can outperform on the GMAT. Good luck and keep focused!

SAT: 1390/1600 (730M, 660V) 

GMAT: 740 (49/51 on quant, 41/51 on verbal)

I thought it was pretty easy to break 700+ on GMAT after studying math/engineering in ug due to GMAT being a very logic-heavy exam. I had issues improving my verbal score, specifically sentence correction. 

Also, I went to a weak public HS (avg. SAT of ~1000/1600) and wasn't really aiming for top schools, so I remember being pretty happy with the 1390/1600. For the GMAT, I was targeting 760+ from the onset and made sure that I was testing at that level before taking the actual exam

1520 770 Use common sense

ACT: 31 (was 96th percentile at the time, didn't study at all), SAT was around 2100

GMAT: 730 (was 96th percentile at the time, studied the math portion for several months)

There will likely be significant correlation. However, I've seen more people who did well on the SAT/ACT struggle with the GMAT than the other way around. GMAT has a little more "problem solving" to it. People hate on it but I actually think it's a great test. Instead of random vocab it's logic and grammar and quickly solving or estimating on the math side.
