Hello Bhupendra, 

                   See its always difficult and meaningless to assure a college before the release of actual cutoff for any exam.

                  For general category Compartive to previous year yes you may get into NLS but yes one may not be assure of what will be the cutoff this year as the trend changes almost every year. 

                 155 in CLAT 2019 is a goof score and thus you may have chances to get into NLS.

Good Luck
