Question about Hacking certs

[War Mongrel]

I just recently got the Advanced Hack Cert.

My question is: Is it necessary for me to keep the first hacking cert or am I allowed to unlearn the first hacking cert without losing any benefits since I now have the Advanced Hack cert?

Can't be untrained. Hacking is a pre-requisite for Adv. Hacking
