@angie333: Don’t stress, there is nothing to be gained by worrying about it now. Just try to enjoy your Senior year. Take a few slow, deep breaths every time you think about your application. 
Both of my daughters received their admissions offer in mid February (in 2012 and 2017). So there are still 2 weeks left before that time for this year. And with the Harvey delay and probably many more applications than the 42,000 that were submitted and 27,000 applications that were reviewed for Fall 2017, so it will probably just take more time this year.
I have heard that in the '90’s that sometimes people didn’t hear until MAY whether they got in or not!! I think they used a
“wait list” back then. I don’t think it will take until May for everyone to hear back this year. I do think that starting the application period on July 1 was probably not a great idea, but they didn’t know that Harvey would hit in August and delay some of the testing dates. Extending the deadline probably led to even more applications than there would have been if the deadline was Dec. 1. There are so many qualified people who want to be an Aggie, but there just are not enough seats for everyone.
A lot of people have been upset with the lack of firm dates for offers, but we have to remember that the reviewers are people, too. The have a tremendously difficult job, they know that they hold the applicants futures in their hands and I am sure that they want to make the best decision for the applicant and TAMU. I don’t know how many people that are in the applications review department, but perhaps some of them were affected by Harvey. Or possibly they or their family members were affected by this terrible flu season. Or maybe there were other illnesses, injuries, or even deaths in their immediate families. We don’t know what difficulties the reviewers are experiencing. And if there are 100 people in that department, they are each reviewing many thousands of applications. Hopefully, there are more than 100 people in that department, but the work load still has to be huge, no matter how many reviewers there are!
According to TAMU, an application may be reviewed several times by several people. And that takes a lot of time, but it is a great thing! Although a computer would be much quicker to use to decide to admit or deny, a computer sees only “black and white” and can’t tell what is special about each individual. I am grateful to the reviewer(s) who saw something special in my younger daughter and offered her Blinn-TEAM. Her gpa (3.5 unweighted) and SAT (1250) were average for TAMU but her class rank (53%) was very low. Less than 1% of TAMU Freshman were below the top 50% of the HS class. I am glad that they looked beyond her rank!
Just hang in there! Get info on all of the possibilities and decide what you will do when you receive the offer, no matter what it could be, (full, Gateway, Blinn-TEAM, PSA, denial) so that you are ready when the decision arrives. I hope that you receive a full admissions offer, but remember, even if you are denied, if you really want to be an Aggie, you can always transfer in later. There are just so many qualified people who want to be an Aggie and there are just not enough seats in the Freshman class.
Last year (Fall 2017), out of the 27,000 applications that were reviewed, there were only 3,800 offered full admit, 530 offered Gateway, 2,400 offered Blinn-TEAM and 855 offered Blinn Engineering at Blinn-Bryan. So out of 27,000 reviewed applicants, only 7,585 were offered a level of admissions which gave them the opportunity to start out as an Aggie in Aggieland. There were 10,500 students who were offered PSA, starting out at another campus and planning to transfer in later, and several thousand students were denied admission to TAMU, receiving no offer. But again, if they want to be an Aggie, anyone can apply to transfer in later.
Hopefully you will receive an offer of full admit! But just don’t stress, take slow, deep breaths instead!
