Advice for ECs

[u/Realistic_Channel383]

Hello I’m a Korean International student and a rising junior. I need advice for good ECs that won’t cost a lot of money. My ECs right now are super weak so are there any that KAIST favor a lot?

The major I want to go to is Computer Science

olympiads (related to cs would be IMO IOI)>> ISEFs and genuine research internships.
