Dear Nandakumar,
According to the previous year cut off for state quota self financing medical College either controlled by government or private entity for general category students was less that 530, ranging from 528- 481.
So if the previous year's trend continues then you have a fair chance to get a medical seat in a self financing medical College of Kerala.
Keep in mind that year cut off fluctuates so this year too the cut off may variate.
You can check the cut off for each medical College which is self financing from the link given below.
