With a CUET score of 729 out of 1000, it's possible to get into BA Political Science programs at some colleges within BHU, AU, or DU, but it depends on the specific colleges and their cutoffs. Scoring 729 is a decent score, but competition is high, especially for popular colleges in DU.

Rejoining a B.Sc (Hons) Physics degree at Delhi University after leaving in 2018 would be extremely challenging, if not impossible, to continue from where you left off. DU usually has strict regulations regarding discontinuation and re-admission; a gap of several years typically means you cannot simply "continue" the old degree. Your best course of action would be to contact the Registrar's office or the specific Physics department at your former college/university to inquire about any possible re-admission policies or alternatives like fresh admission.
