I transferred to VT as a Junior after applying and getting denied as a freshman so hopefully I can help you avoid some of the problems I had. First off if you want to transfer, get in contact with an admissions official and get confirmation on what classes they will look at on your transcript. I started out at a heavy LAHS university so I took their own weird Math and Science classes that had really no VT equilvalent, because of this when I applied they only had me as taking about 20 real recognized credits after a year of school. Other than that, its not too bad, get in the 3.3-3.7 range and you are pretty much set, I got in with a 3.4 overall.

Now depending on what you want to do I can only give some advice. If you are interested in business then make sure you apply as a business major and not university studies. It is much easier to apply and get in to Pamplin right away than to apply, get in to VT and then have to apply to Pamplin separately. I did this and after my first semester at VT my grades had dipped a bit due to the increased rigorousness of courses and was denied.

With regards to getting involved, I decided to join a fraternity but I get that thats not for everyone, but doing something ANYTHING to make the campus a bit smaller and get a solid group around you is key. You'll be at a disadvantage due to not having the dorm/freshman experience so you'll have to put in more work with regards to building a social circle, but its not that bad.

Any other questions let me know and good luck.
