Confused about University, Foundation Year, and Offers

Do you need an offer to get into a Foundation Year? And Do I need an offer to get into a certain university?

I'm a junior high school student in the Philippines and since my hs diploma won't be enough for direct entry requirements, what can I do to boost my chance for an offer? Are all the requirements (from UK or Australian unis) based on grades alone or also extracurricular activities? Really confused and lost TOT

"you apply to university after senior high school, K 11 to 12. Is this correct?"

yeah, that's correct. what does it mean to do level 3 qualifications? and does UCAS also need any A-levels or is it just a registration thing? thanks!

Universities require you to do level 3 qualifications: which are equivalent to your qualifications you gain after completing K12. Some courses only require you to have certain grades, others require specific subjects . As international students are applying with different qualifications, UCAS points are used. It convert your grades to UCAS points.
UCAS is only used in the UK (I am from the UK).

UCAS allow you to apply to UK university courses.

I'm a junior high school student in the Philippines and since my hs diploma won't be enough for direct entry requirements, what can I do

so if i apply thru UCAS and get an offer, I will have to do a Foundation Year because I didn't get any A-levels or IGCSE?

What qualifications do you get after completing K12?

Look at doing an International Foundation Year run by a Uni that offers the main degree that you want to do.
For these you do not apply through UCAS but directly to that Uni. If you successfully complete the IFY then you have automatic entry to the main degree the following year.

Examples :
University of Bristol - https://www.bristol.ac.uk/study/undergraduate/2024/international-foundation-programme/
Queen Mary, University of London - https://www.qmul.ac.uk/international-students/pathway-programmes/ify/
University of Kent - https://www.kent.ac.uk/international-programmes/international-foundation-programme
Etc etc.

Do i still need an offer from the uni to get into an International Foundation Year or can i directly enter it thru the uni? thanks for the info btw!
