I am another MS4 at Sackler, and I want to share my perspective on the things that have been discussed here.
1. Why do the numbers seem to bleak?
I think it's important to put these numbers in context: the class of 2018 was an outlier year and we should not assume that future years will be like that. The students in the class of 2018 who graduated on time (~70%) did very well, and had arguably the best Match in modern Sackler history. However, those who didn't graduate on time really struggled. We currently have 8 students from the class of 2018 who took one year off. I do not think this is excessive. However, there are six(!!!) students from their class who are MS3s now after taking two years off. All of them have at least one exam failure that forced them to take a year off; some have two. To put things in perspective, there is only one student from the class of 2017 who took two years off, and that was due to an unforeseen medical issue, not exam failures. The class of 2019 only has one person taking two years off, and that is because they want to do research because they are vying for an extremely competitive surgical sub-specialty.
So when @Drwhip says that 13 extra students joined their MS3 class so far, keep in mind that half of them are stragglers from the class of 2018 and that this is definitely not the norm.
Now, I want to address why Sackler students, who didn't fail their Sackler exams, choose to take time off during medical school. One reason is that some Sackler students are going for very competitive specialties and need very high board scores and published research to match into these programs.
Know that if you are interested in a very competitive specialty, such as a surgical sub specialty (eg ENT, neurosurgery, etc.) you will almost definitely have to take a year off.
A second reason has to do with the students themselves. Most students choose Sackler because they didn't get into US schools, which is usually because they have low mcat scores. If you are someone who struggles with standardized tests, that's not magically going to change when you get to Sackler. So several students take a year off so that they will have more time to study for the USMLE so that they will have better scores. I want to make it clear that this has nothing to do with Sackler's curriculum. I happen to think that the pre-clinical education is great and prepares us very well for Step 1. The students who need extra time to study for Step 1 (who are not going for competitive specialties) would struggle at any school, and it's not fair to blame Sackler for that.
2. What are the numbers?
Now, onto the actual numbers of the original class of 2019. We started out with 63 students. We have only two students who had to take a year off for failing Sackler exams (one of them didn't come back). We have two students who chose not to come back after two years at Sackler. We have seven students who took a year off after year two (including one person who failed a Sackler exam), and five who took a year off after year three. We have four students who will be doing residency in Israel and are not applying for the Match. So we have 49 out of 63 graduating on time, and 45 out of 63 applying for the Match on time.
I don't know how these numbers compare to other schools, but my guess is that this is better than most other US IMG schools. Don't assume the grass is greener elsewhere (unless you're comparing to a US allopathic school).
3. What happened with Step 2 CS?
Yes, the rumors are true. We had 13 people fail this licensing exam last year on their first attempt. I don't know which students failed, so I don't know why this year was such an outlier. I will say that the people who I spoke to who passed CS, including myself, struggled the most with the medicine, not with shyness or empathy. I'm assuming the same was true for the students who failed.
Most years only one or two students fail CS. Only two students failed the year before, for example.
Fortunately, the school has already made changes in the curriculum to start CS prep in the first year of medical school, which was implemented starting last year (ironically before they knew CS would become such as issue). So while they aren't doing much differently to help current MS3s prepare for the exam, every subsequent year will be much better prepared for the exam.
In short, I don't think this should be a reason for you not to go to Sackler.
4. What are extra challenges that Sackler students have to face as IMGs?
As I said before, the pre-clinical curriculum is great, and if you study hard you will be very prepared for Step 1 at the end of second year. That's not on this list.
However,
you're clinical education is not going to be as strong as it would be in the US. I agree with what was said by others so I'm not going to repeat it.
You will struggle to get your electives in the US. Sackler has almost no connections, so they will not be able to help you beyond giving you one or two "Sackler spots" (a select few institutions guarantee electives for Sackler students, which is enough for one or two electives per student; we need a total of four). Many students had to use personal connections to get at least one elective, and several had to do an elective at a private practice (much less desirable) because they had no other options. On the other hand, I don't know any Sackler student who took a year off simply because they couldn't get their electives.
We are also considered IMGs for the Match; this has been discussed earlier so I'm not going to repeat what was already said about how that impacts us.
5. What are the benefits of going to Sackler?
Most importantly, you will become an MD. Many Sackler students did not get into US allopathic schools, and by going to Sackler you will fulfill you're dream of becoming a doctor.
And if you're willing to work hard enough,
no specialty is closed off to you. We have students matching every year into very competitive fields, so if you have your heart set on a particular specialty, you will most likely be able to achieve your goal at Sackler.
As
@Drwhip said, the other benefits are mostly social and cultural. Because most of us don't have family living in Israel, our classmates become our family. Tel Aviv is also a great city to live in (even if it's a bit expensive).
6. Should you go to Sackler if accepted?
It depends what your options are.
Between US allopathic schools and Sackler: go to the allopathic school. This shouldn't even be a debate for you. Even if you get off the waitlist after you already got to Israel for orientation, you should still go to the allopathic school. The only situation where you might prefer Sackler is if you are planning on going into family medicine or pediatrics, and the allopathic school is much more expensive. No one from Sackler has ever had any trouble matching into those specialties, and the salary for those doctors are low enough that you should consider the price tag of the schools when making your decision.
Between Sackler and Technion/MSIH (ben gurion): Definitely choose Sackler! Any dysfunction Sackler has pales in comparison to the other American schools in Israel. I don't want to be more specific on a public forum, but I can tell you that knowing what I know now, I would rather retake the mcat and reapply to medical school than to go to one of those schools. (Not for anything, Tel Aviv is also a much nicer city to live in than Haifa or Beer Sheva.)
If you are deciding between Sackler and a DO or Carribean school, it's a much tougher question and probably program-specific. FWIW many Sackler students chose Sackler over DO schools.
Hope this helps!
