Does anyone know if you can do anything about being admitted to 2+2 but you wanted university park all 4 years? 
You may be able to call UP admissions office and ask them to reconsider you with a different major. I know people do that if they’re rejected from there.
Usually if you have found out about 2+2 you cant change anything. you may be able to change the branch you go to but they wont change their mind on the 2+2
It truly depends on what you were denied from at UP. What did you apply for and what was your GPA and test scores…That will help in knowing whether you have a shot at turning it around. Many people can ask to be reconsidered and get into UP after being denied or deferred to a branch, but it is highly dependent on major and original denial. What were your stats?
