Importance of Certification courses

Certification courses are the courses with are conducted by some training center or organization . They run some courses like marketing course , web development course , or any other course . And after the completion of the course the training center provide you the certificate as a proof that you have done certification course from their center which you can add on in your resume or CV which shows that you have a kind of knowledge in that particular field . 

Mode of Certification courses:

1. Online

2. Offline

Online certification courses can be done from some of the platforms like coursera , Udemy , Udacity and many more . And also some of the companies like google , microsoft , amazon , etc also organize some certification courses who's value are really worth it and the which may help you in your placement. If you really want to have a certification course then I personally recommend you to have it from the companies that I mentioned above because that certification course can really add a value in your CV or resume.

Offline certification courses can be done from any training center or coaching center but that will not really help you in your placement because many training centers provide you the fake certificate and that's the reason companies don't believe the certificate from any coaching centers. So kindly don't waste your money in some coaching center certificate courses. Because they don't really worth it.

If you are preparing for online placement then the certification courses are not really needed just focus on your knowledge in that field and it will help you to grab that placement or crack the interview.

Best of luck👍👍👍👍👍
