Hello Iqra Ruhi !
See,the cutoff changes every year depending upon the number of candidates appearing for the examination,the category of the candidates and the difficulty level of the examination.
If we take into consideration the previous year cutoffs,a score of 350+ will help you get a seat if you belong to General category.

Hope this helps.
Good luck.
