Can you please say the list of colleges in which I can take admission for b planning with rank 1893 in jee mains paper 2 b planning?

Firstly you must know that SPA Delhi admission 2023 for B.Plan and B.Arch courses are over. Secondly, the closing rank for SPA Delhi B.Plan course 2023 is 330 for general category. Therefore, with a rank of 1893 in JEE Main paper 2 getting admission in SPA Delhi is not possible. 

The other option available to you is to get admission through management quota. The fee is generally very high for management quota students. If you want to take admission in SPA Delhi then you must try next year and till then prepare for JEE Main paper 2 and try to secure rank below 300 for SPA Delhi admission.
