Pub 350 will be with prof meng wang and pub 420 with dennis daniels

I'm planning taking both of the classes this semester. Pub 350 will be with prof meng wang and pub 420 with dennis daniels. Is there any exam or if the classes are going to hard?

I would suggest you to get in touch with the professor for this. He can guide you properly. Just shoot a mail to him with your queries. Also do try to find out his website where he mentions his class pattern.
