WES has been issuing varying evaluations for LLB graduates.
People who graduated with LLB from universities like Delhi University where a prior university degree is required to join and LLB is a standalone degree, not an integrated degree, have usually received an evaluation as Bachelor of Laws.
People who have graduated with BA/BCOM/BBS + LLB degrees, and who were part of 5 year integrated programes, have usually received evaluation as 4 year bachelor degree.
However, it is not necessary that you may get the same outcome. You should still go ahead and get your ECA done. I would suggest that you get your ECA done from CES instead of WES as CES has a better reputation in providing more accurate ECA's.
