My score is 336 and I have alc category so can I get a MBBS seat in Jammu Kashmir ?

Dear Aradhya, ALC  Category reservation will come under Horizontal reservation within your Category. It is not a vertical reservation. So the available reservations for candidates of Jammu and Kashmir are SC, ST. The cut offs for various Categories in J&K under State Category of 2018 are as follows:

OM: 440
SC: 361
ST: 266

So with 336, unless you belong to ST Category, a seat might be difficult. Having said that, cut offs change every year and are dependant on various factors like no.of seats available, no.of candidates appearing for the exam, top NEET score and difficulty of the exam.
