Do universities see the whole score breakdown that I got on the collegeboard together with the overall score ?
For example , the number of wrong answers and the percentiles ?
I’m pretty confident they see everything as far as breakdown and percentiles. It didn’t specify number of right and wrong answers. I only noticed this because I was checking to see if the college received everything and the SAT section had a lot of specialized abbreviations and percentages.
Do they see the test date?
Just checked and the answer is yes. The format aside from test day looks like the following, but I omitted all of my child’s scores and percentiles. AHSSC: ASC: CE: EBRW: EI: HA: MATHS: MT: PAM: PSDA: READ: RWC: SEC: WLT:
Lol. I only know what two of those mean.
Yes
Probably better that you don’t. 
It’s just going to add stress to students who will wonder if one section will doom their chances.
Anyway, before anyone freaks out, AO’s are not going to microanalyze these subsections. There’s neither the time nor the inclination, particularly since this level of detail is new.
What the heck? I always assumed they saw the two scores (out of 800) and the three sub-scores (out of 40)!
Wonder if it makes a difference if the student the test very early junior year and only sent one score. To me that should mean something but, again, who knows if they have time to notice.
Thanks for the responses ! I am actually happy to know that universities will get so much information . In this way they will see that I did everything almost perfect , with the exception of two reading passages (their questions of course) that were with history , and I have nothing to do with history for my major (geophysics/geology/astrophysics) . Maybe the admission officers will be like : "Wow ! He is really bad at understanding old english , but he is an international student so it is somewhat understandable … " 
You are overestimating the amount of microanalyzing an AO will do in the 10-15 minutes s/he spends on each application.
Ok , I have exaggerated a bit (but still happier than just seeing the total score) .
I suspect that they will have time to do a quick check of the CRW score (200-800) and the Math score (200-800) to see they pass some threshold and move on.
What?
It doesn’t matter how much detail they send electronically, only what is then formatted on the app the adcoms see. And that’s the M and EBRW and/or ACT composite and subscores.
Nope, no microanalyzing. Nor assuming, guessing, or filling in blanks for you.
Not sure @wheatonmom is seeing what adcoms do.
