Hello Aspirant,

A certificate is earned by a student after taking a series of courses in a particular subject. Students often earn certificates to get a step ahead in the professional field of their interest, and certificates may be offered in similar programs leading to degrees.Diplomas are similar to certificates, and they're often awarded through community or technical schools. Diploma and certificate programs taken alone are similar to associate's degree programs. However, they take less time because general education courses are not required.
I'll recommend you to go for diploma program.
