There has been no indication that they will not use second semester of junior year grades. If you have seen otherwise, you can give a source.
All schools were different and students could explain in the additional info if their grades the second semester were impacted.
To be clear, UCs said the following about P/F classes and second semester of junior year. This is from UCIâs site:
Pass § or Credit (CR) grades earned in spring 2020 through summer 2021 will meet A-G subject requirements but will not be calculated in the GPA. UC will continue to calculate the GPA for admission purposes using all A-G courses passed with letter grades in grades 10 and 11, including summer terms following grades 9, 10 and 11. Extra points in honors-level coursework will continue to be capped at 8 semesters of honors points in A-G courses completed with letter grades of A, B and C in grades 10 and 11.
In short, they are considering 2nd semester grades. The kids who got P/F wonât have their GPA penalized, and the kids who did get letter grades will continue to have those considered.
Maximum Capped weighted is 4.4. UC GPA calculator is here: GPA Calculator for the University of California â RogerHub
UCâs also look at Freshman grades but are not included in the GPA calculation. OOS/International studentâs Honors classes are not given the extra honors point in the calculation and only UC approved Honors classes for in-state students get the extra honors points in the calculation.
The capped weighted although listed in most of the UC statistical data is more of a threshold that in-state and OOS/International students need to meet to be eligible to apply. 3.0 for in-state and 3.4 for OOS.
The UCâs look at all grades and courses listed on the UC application. Senior grades are not considered but you need to maintain good grades to keep your provisional admission.
High stats kids who were pass/not pass for spring lost the chance to raise their GPAs by adding in more 5s. They are penalized.
The OP was saying second semester grades werenât being counted at all due to pass/fail. Thatâs not correct. They are counted, and while yes, they are penalized for not adding in more 5s, they arenât being penalized from the standpoint of the grades ânot counting.â If they didnât count second semester grades at all, the kids who did get letter grades would then be penalized. I guess they had to make some sort of choice one way or the other.
And kids who take more than the required number of classes have their capped weighted penalized as well (but thatâs every year).
Kids with all 4 semesters of grades would have needed 2 honors courses per semester, while kids with pass/fall would need 2 and 2/3 classes on average per semester. Iâm guessing the admissions officers would know how to manage this data. Hopefully, itâs not make or break for any students but there is really no way to know.
Kids who take more than the required number of classes are not penalized. Uncapped is considered and I suspect it is the primary GPA consideration at UCLA and Berkeley
The counselor at my kidsâ school said she heard at a UC counselor meeting that it would be taken into consideration but there has been no elaboration and no one seems to know how.
My kid had 6 academic courses for 3 semesters. P/F for the 4th. No APs in Sophmore year. All Aâs and yet very low GPA like 4.17 or something.
The UCâs have always been GPA focused so without test scores, they still have 13 areas of application review criteria to based their decisions.
really? but donât you have to have a 3.0 weighted? I thought UCLA was the one who only allowed 1 CâŠ
Omgeeeee i am so confused by these GPA posts 
Now I am more confused than ever about how it all works
UCLA and UCBâs provisional admission contract spelled out no more than 2 Câs Senior year, unweighted GPA of 3.0 and no Dâs or Fâs. The other UCâs state you need to maintain a 3.0 weighted GPA Senior year no Dâs or Fâs, but this can always change.
I think weâre using penalized differently. Iâm probably not being clear. I was speaking of how the capped WGPA can drop the more classes you take, even though you still get high grades. Itâs a penalty from the standpoint that it doesnât tell the whole story for the student, just as those P/F grades also dont tell the whole story.
I think itâs been mentioned multiple times here, though, that capped WPGA is only looked at to determine eligibility anyway.
Curses to all of you (and now to me). When I come on and see 100-something new posts in this thread, I just âknowâ itâs happening!!! And then I look, and nope, itâs just all of us anxious people being anxious. 
Ugh.
lol, if admissions was really bluffing a bunch of people will probably check the portal anyway and crash the server regardless
And the capped weighted GPA is usually the GPA referred to in the UC statistical data for admitted and enrolled students. Exceptions are UCLA and UCB which actually show the Fully weighted UC GPA on their websites.
Donât worry about it too much. Itâs out of our hands now anyway. 
I do think the UCs make it overly complicated and it causes a lot of confusion. Whatâs most important is strong rigor and great grades. Thatâs the bottom line. Hopefully, they came up with a solid way of fairly assessing the kids who had P/F grades.
Do you think 4.13 capped GPA and 4.5 UC GPA good enough for UCSD
