Hello @viktor_mex
always feel free to ask here. The certification in not only a proof that you passed some tests. You will need some (more) real month of hands on experience to pass easily. How ever, why not starting the path and go step by step forward. Even if you turn back later - there is not pressure. Would be a nice goal to archive the certification at the end, isn’t it?
I am aware that as a student there might be not extremely much time left to dedicate to “just one” specialisation but if you build the basics you might be able to pick up in the next seminar and surprise others with rapid development which is indeed one of the many major pros of MongoDB.
Best of luck
Michael
