Hey Rasika.

 The amount of marks that you would require to score in CLAT for a fair chance of admission in NLU Mumbai cannot be accurately predicted at all.

In the previous year the marks required for admission in top NLUs were around 150+ but it changed to 130+ marks in the next year. The poing being that it keeps on changing each year due to several factors like level of competition, level of difficulty and much more. Hence an accurate presumption for marks cant be made in CLAT.

The ranks required remain similar though. The cut off  rank for admission in NLU Mumbai in the previous year was 503 for the general category. Hence you can expect a similar range of cut  off this year too.

Best of luck
