Thanks for the explanation. Not sure why I'm missing this, but can you please explain what the rule is that lets you convert (1/4)^18 to (1/2)^36?
Also, can you please explain how you converted [ 1 / 2(2*5)^35 ] to (1/2)^36 * (1/5)^35 ?

Maybe nobody is familiar with these programs? I think Thunderbird might offer the best experience with the largest network. I think Indiana might be best in terms of education and the "name" of the school. Florida I think has a solid overall program and is known to be a good online program...

Not crazy high scores here....I think my highest was a 35 in Verbal and 35 in Quant. Verbal, I do really well on CR. Sentence correction has been pretty messy. Quant is okay and I will be drilling out as many problems as possible over the next three days, but I don't see any huge jump being possible...

Need some encouragement!!!
Hi everyone, The GMAT is next week for me and I'm starting to second guess my skills in quant. I only need a 550 which is very low, but still I really don't want to have to repeat this thing.

Would you learn probability + rates in last two weeks?
I only really need a 550 on the GMAT, although I'm aiming for a 600. I have most of the math concepts down and have done many OFG13 problems, but I have a bunch of them flagged (thanks BTG for the great prep chart!) that I need to spend significant time learning and reviewing. I haven't spent any ti...
