hello,

the basic eligiibility criteria to pursue the B.DES is candidate must have passed 12th grade or equivalent examination and as per your question there is no restriction of stream chosen in 10+2  which means students can have any of the stream like science, humanities and commerce , the age limit to apply for this course is 199 to 20 as specified by the institutes at the time of admission

i have just told you the basic eligibility criteria however it may be vary institute to institute

good luck!.
