You have completed the course from outside, so how you will 
apply as a fresher? What you will say? self made consultant?
You have to give s fake experience of atleast 2-3 yrs.So 
you know the fate, any time you will be caught and thrown 
away.If you have learned from out side than you know only 
20% of what people learn at authorised training centre. So 
if you are confident than better go for certification, you 
will get a job definitely.
