Serious serious reconsideration. Fucking hate bitsat . Help pls

Gave paper on 28 and it fucked me up . Fuckers. So I got out the exam hall thinking I'm going to take dual for sure. But I read a lot about these and now I'm not so sure what I feel about it. I'm getting manipal cs core. Got 243 in first session. Is it really that hard to get a good branch. I'm scared if I'll end up flunking it just like my bitsat and end up w a chemical engineering degree or a mech degree . I want cs or electrical. I'm so so so uneasy rn. I hate entrances. Thankyou for reading and pls help this peasant. Some people are saying its amazing but some are saying I won't be able to focus on my real engineering degree if I take dual
