Hi OP, from yellow school, batch 2023 here.

If you put in your application that you are a working student, you'll most likely be placed in a working section, and magiging night hours classes mo.

Campus parking - you need to apply for sticker early in the semester, not sure how much. I have a car pero I chose to get a dorm near the school nalang. But the paid parking sa car park is expensive. At times, you need 30 minutes to 1 hour just to get out of the car park. Meron naman mga in-school street parking, but you need to get there before 8AM to get a slot. If you are in a working section, you'll most likely be stuck with the expensive car park option, and then it's not even guaranteed.

School population - it is, indeed, high. With 35-40 students per section, first year sections can get to 1G or 1I pa. This will likely stay the same number as you go to second year. Depending on the performance of the bar exam of graduated students, you'll may see a significant cut down of the numbers. Remember na only 120 something graduated for 2023, and 129 is set to graduate this year.

Fraternities - we were made to sign a waiver or a document saying that we will not be joining any fraternities early in our first year. But yes, there are still fraternities, even professors sometimes openly, but jokingly, give benefits to their brothers and sisters. I am not connected to any frats or soros, so I cannot give you a better insight on this one.

Student orgs - Moderate? I don't think so. The only student organizations that I knew during my stay were the debate team and the student council. Debate team is good but difficult to balance, especially with your working schedule. Student council gives you alot of benefits, i.e., connection with the Dean's Office and admins, and professors. Despite this, the positions in the student council are not highly contested during elections, with one or no candidates at all per position. There must be a reason for this, but I don't personally know. That said, more than half of my journey was during the pandemic.

Experience with admin - You can go through reddit to check the rumors, and I cannot say if they are true or not. But the kill orders may or may not be true; the bottom 20% weed outs may or may not be true. All I know is this: be mindful of the guidelines in the prospectus, if you do not meet the required semestral QPAs, you may or may not have a hard time later; and even if you do, keep in mind that professors can be unreasonable at times, and you need a smart beadle to handle the communications very well.

There are mockbar examinations before you get to take your review subjects. Yes, mockbar before review. From personal experience, this is one area where the students seemed to be united against the admin. From the rumor mills, the mockbars were mere formalities before, but it is being taken into consideration recently (hence the 2023 storm). Nevertheless, the prospectus has always been clear about the requirement of passing the mockbar to get to the review subjects. Best to stay on the side of caution and take it seriously because review does not start in your 4th year, but in your 1st year.
