CS Executive June 2025

Hey everyone! I needed help with some procedural things with the Executive examination. Saath me dena compulsory hai or can we pick just one to give? What's the pre-exam test? Agar fail hogaye, then wapis 17,000 dena hoga?

I know these questions can be answered elsewhere too, but I also want to make some friends who are also preparing for Executive June 2025. I'm from a STEM background, so my circle consists of mostly engineers and data guys. Thanks!
