hi,

see to pursue b.a or b.sc course you need to pass 10+2 course from a recognized education board. since you have completed your 12th course you are eligible to apply for ug courses in college, however this 1 year aviation course certificate is not valuable or have much preference for ug admission, becuse degree colleges evaluate your 10+2 course and your admission in b.a or b.sc is done by on the basis of your intermediate marks,

however in future you can mention about this course in your cv.
