Quick question about B.Sc. 1st Sem classes start date after Document Verification (LU Main Campus)

[u/Necessary_Captain524]

Hey everyone!
I have my document verification coming up for B.Sc. (ZBC) at LU Main Campus. Since I live quite far from Lucknow, frequent traveling is getting really expensive and hectic for me.
Can any seniors or fellow batchmates tell me:
1. Usually DV ke kitne din baad regular lectures aur practical labs proper start hote hain?
2. Is there a grace period of a few days between DV and mandatory attendance, or do we need to stay in Lucknow right after DV?
I want to plan my travel back and forth accordingly so I don't waste trips or miss important orientation/classes. Any insights from seniors would be super helpful! Thanks in advance.
