Hi all
I have 3 weeks until the big day...

I am a bit confused on what should i do from here
I have finished Og 10 & 11, kaplan and princeton
i am half way through the 1000 series in cr and sc

i want to practise more maths problems especially some difficult ones.
verbal also i need solid testing practise

can anyone suggest me some useful material i can complete in 3 weeks?

Does doing the sets 21-30 help?
Should i do the ETS paper tests? it follows the old format though

Please adviceeeeeeee.....
