You've posted WAY too much information.

Your GPA is going to hurt you, a lot. Even knowing that you are in a difficult major often have much lower GPAs won't help you a lot. The Greek life office and nationals aren't "upgrading" hard major GPAs when they take chapter averages into account, and you'd be viewed as a high risk for being able to handle the responsibilities of Greek life.

I would suggest focusing on summer school and fall to get your grades up. If you can, meet women in sororities to prepare you for COB. Look into spring COB.

As for "competitive houses" - they are much more likely to make grade cuts high above their "minimum GPA requirement", and will be unlikely to have spots open for COB in the spring.

Cal and UCLA both have upperclassman quotas. I don't know if that includes sophomores or only juniors/seniors at Cal, but it appears to be small (4 last year vs. 41 freshman quota). At UCLA, the upperclass quota includes sophomores and is roughly 1/3 of pledge class size - it helps bring in both sophomores and juniors into even competitive chapters. But in that case, the juniors are typically transfer students, and it would be suspect that you aren't.

Here are your options:
1 - Rush this Fall: Be prepared for massive cuts based on grades. More cuts for class standing. If you get a bid, you'll be in a tough position to keep your grades up and fulfill sorority obligations.

2 - Wait and/or try again for Spring COB: Be prepared for a limited number of houses to have spaces available, but your sophomore standing might not be too much of an issue.

3 - Wait and/or try again for Fall 2015: Be prepared for massive cuts due to your class standing. If this is your second/third time going through recruitment, be prepared to answer questions as to why you're going through again.
