I find this whole PTE/CTE thing confusing. If I get an acceptance to school X and select PTE for that school, what can other schools that I have interviewed with see while making their decision on me post-interview ? Can they see which school(s) I selected PTE with ? And how does this differ between now and 4/15 ? 4/30 ? After 4/30 ? Is all this stuff documented somewhere ? Seems misunderstood by many (including me).
Unless a school gives you a WL or A, and loads it into the AMCAS system, they can never see anything about you, until the end of the cycle (next October, when they will be able to see where everyone in their pool matriculated).
Prior to 4/30, if you are A (but not WL) at a school, that school can run a report to see, in the aggregate, whether you have selected PTE at their school, another school, or no school. The report cannot be run on an individual applicant level, so they will not be able to see what
you have done at all. This is why I don't think it makes sense to even use the tool at this point, unless you are afraid you are going to forget to do so by 4/30.
On (or after) 4/30 (it's unclear whether this is actually 4/30 or 5/1), schools can require you to select PTE to keep your A (most will), so that's your deadline to reduce to one A. You can keep all WLs until the CTE deadline at the school you are PTE at, at which point you are committed and your cycle is over.
After 4/30, schools can see, by individual, which people with As or WLs have selected PTE or CTE, at their school or another one, but they can never see the identity of the other school. This is how they enforce their deadlines, and kick people off the WL who have CTEd elsewhere, and rescind As from people who have PTEd elsewhere.
Yes, it's all documented on the AMCAS website, but it's kind of hard to follow, which is why there is so much confusion.
