Yiur 12th scores shall not affect your placements but in sone companies where the re is criteria based on all marks there you might be not eligible.





But chances are rare for such conpanies.



Try to maintain more than 8/10 CGPA or 75%and abive to get good companies.

Placements alos require good deal of communication skills and internships experience which is must.
