First of all it greatly depends on your state for which you are eligible for applying.Consider if you are from home state and your state has good number of college than getting into some reputed college would be easy as state gives lot of privilege over the students of there own state.

On the other hand ,its equally diffiucult if you belong from open state for that college.The marks and ranks needed shoots up too much!

With 105 and home state i would say you would probably get a good college!

Start applying in all the colleges separately!
