I have planed to apply to grad schol this year. 
 
However, I have got a bad GPA, GRE, GRE CS and also TOEFL. 
My GPAs are 2.01 in B.Eng, 3.65 and M.Eng. (Computer Engieering) 
My GRE is V/Q : 290/790, and Subject Test is at 50th percentile. 
(I took a test 2 times this years, and still waiting for the second score.) 
 
 
I also took TOEFL test 4 times, all are bad and not consistent. 
Reading/Listening/Speaking/Writting 
1st : 17/26/14/24 
2nd : 26/24/15/17 
3rd : 27/18/15/17 
4th : 23/22/18/21 
 
Despite the low score, I've just submit a paper to high rank conferences 
in filed of theoretical computer science, STOC. I have a confident that 
this paper would be accepted. 
 
I'm nearly to give up to apply to grad school. 
Am I have a little chance to be admitted by any grad school.
