@PepsiMakesItOk - You seem like a strong candidate. but it is difficult, if not impossible to give any meaningful chance assessment.
Here is a thread, about chances, from @maryversity who is very knowledge about UMD, particularly Engineering

It is easy to transfer into Engineering, once you have completed the Gateway courses. These are the same courses that direct admit Engineering students take.
Here is another thread with lots of replies from @maryversity again.

Make sure that you apply by the priority deadline (Nov 1) to be eligible for Merit Scholarships and Special Programs.
Also, UMDCP can be expensive for OOS students and they do not give out a lot of large scholarships.
Good Luck
