First, does your highschool gpa have any affect in the admissions process? I'm under the impression that you are not required to send a HS transcript in with your undergraduate studies but I'd like a clear answer. Personally I wish I could just erase that 4 year span academically as it does not reflect my current level of motivation or interest at all

Second, I attended my freshmen year of college at another University than the one I currently am enrolled in and will attend for the next 2 and a half semesters (Currently a Sophomore at the University of Texas at Austin). I made a 4.0 at the first college (University of Texas at San Antonio) and I'm wondering if those grades will be counted the same as my Austin grades. UT Austin is a more prestigious than UTSA is and the classes are much more rigorous here, will that change in difficulty be noted? Any and all information on this area would be extremely helpful.
Thanks.
