BA LLB ET

So guys, does ET matter so much? I am preparing but I'm scared seeing the questions in RS Agarwal for Quants and I gave up on GK because I am weak. What do I do? My exam is on May 9th, can anyone tell me how the exam was like what kind of questions? I didn't apply for Round 1. If I mess up the ET, will I not get in in Central Campus? Please tell me
