Epq a levelWatch
Also, does EPQ need good english level because im not that good
It depends on who you talk to, but one of the benefits of the EPQ is definitely the ability to enter university more easily as it tends to lower the entry requirements by a grade (I was able to get admitted to the course I wanted to do as a result of my EPQ). However, the EPQ does bring other benefits, such as research skills, independence, time-management, and many more. The EPQ can also be mentioned in your personal statement to show your 'passion' for and dedication to the subject. I would highly recommend taking it (though there are of course circumstances that I would not recommend it).
A good English proficiency (level) does help in an EPQ, but the scores aren't really based on that. Instead, it's primarily based on the planning and research process rather than the product itself.
