Graduate level course work for category B

[alaskat]

Dear all,

I'd like to ask a question about if graduate level courses can be used to establish the completion of Option 4 in category B. I have taken Molecular Biology classes for Bio majors in grad school, and I eventually received a PhD degree in Computer Science (Bioinformatics). Can I use my grad level Biology and Computer Science class?

Also, when I have the burden to establish the eligibility to OED, do I write a letter and show the class descriptions? I guess my question is the preferred format of the letter.

What if the USPTO determines I need more credits? Is there going to be bad consequences for making future applications?

BTW, my undergrad major is Informaiton Science.

Thank you so much!
