I am a FilAm, I went to college in the US, had too much fun, then went to the Philippines for medical school. I went to FEU-NRMF and graduated from there recently.
Before you consider going to the Philippines, you must consider many factors. If you have been educated in the US, the testing in the Philippines is much different, not as analytical as here at home. This poses a challenge, as many of your classmates may be 3-4 years younger than you and able to memorize much easier than you.
You must also realize that there is a stigma attached to foreign medical graduates aka "IMG's". I feel that my medical education in the Philippines was great, and when I did some clinical rotations here in the US as a fourth year clerk, I found that my knowledge was up to par with the US students. It took time to gain confidence and realize this though.
Regarding the schools there. You must go to a school recognized by the WHO, otherwise you will not be able to practice here. UP, UST, FEU, UERM are the big four that have been certified the longest. De La Salle, St. Lukes, are also most likely certified and Fatima might be.
UP- the best medical school in the Philippines, but difficult to obtain admission unless you know someone there and have NMAT scores that are in the 99th percentile. Some of the students are arrogant and spoiled. But they produce great doctors and send 1/3 of their graduating class here to the US for residency.
UST- very good school, small class of Fil-Ams, ranging 5-15 per year. Known to spoon feed there students, meaning they tell you what to study, which is very helpful. Many come back to practice here in the US. Theoretically these students are very well prepared. 10,000 dollar donation fee
FEU- a very, very tough school. FilAms- 2-6 per year. They weed you out as you go along. 1st year starts at 400+ then graduate 150 of original batch. Does not spoon feed, meaning for every exam, they will tell you to read a chapter, and basically everything is fair game. If you graduate, you are very very prepared clinically and theoretically. Challenging school, requires a mature student that is well motivated. ( i think I was just lucky) In recent years, nearly all of the Fil-ams have obtained residency here in the US. 6, 000 dollar donation fee
UERM- good school, rumored to be in Financial difficulty in the past years. Problem based curriculum, which has it pros and cons. Students are good debators, theoretically pretty strong, and fair clinicians. FilAms- 6-10 maybe per year. Most come back and obtain residency here. donation fee is between 5-10,000 dollars
Fatima-Reputation is not very good. They have high passing rates for Philippine boards, but take it in February rather than September (when most graduates take it), which allows them to boast that they have the most top notchers. Many students go here when they fail out of the other schools in the Philippines. Have a large Fil-Am population and a large number of other International students because they are the only school that advertizes. They have a slow track, where you take longer to finish, but are supposedly taught better. They offer clinical rotations to 4th year students, but you must pay a lot. Don't know how may fil-ams pass their boards and come back, but I am sure some do. Donation is 5-10,000 dollars
St. Lukes- good school, requires 5 years. Nice hospital, not too many fil-ams here. not too sure about the amount of donation required.
Overall though, the quality of the edcuation in the Philippines is okay, you will get a good level of knowledge. But regardless of what school you go to, you must work hard. You will find that you will study harder and longer than you ever have before. (And you will realize that if you had done that in college you would be in medical school in the US instead.) All classes are taught in english, jokes are in Tagalog. It helps if you speak tagalog, so your classmates will feel more comfortable with you.
I had a great experience there, it was initially difficult, but loved it there. But use it as your last resort, most schools start with a large class, then weed out students as you go toward 4th year. So there is no guarantee you will finish, and also even if you finish, there is no guarantee you will obtain residency here.
Thats my two cents. Hope it helps
