For AAU,,, sera feto adis gebi yemefeten yelem😂.. so don't worry.. most likely it will be by placement For ASTU and AASTU, you will most likely pass if you take the entrance exam. I heard everyone pass😂... but I heard AASTU is not a good campus. For St. Paul's, it is competitive. They take like 10% of applicants.. there is cut off point from matric result. High school transcript is also seen. There are written exam and interview But don't get into a field you don't want just for the sake of being in Addis.. don't get into astu/aastu if you are not interested in tech or engineering fields. And of course don't apply to St. Paul's if you are not interested in the health related fields. If you are not sure about what you want to study, you better wait for university placement. Hopefully you will get AAU.. but know that there is incredible campuses outside Addis too.. so you gonna be fine don't worry. Good luck!!!
