when the second year notifications will released

Hey!

The question you have asked is a bit vague. You haven't mentioned the University or College in which you are enrolled in and may want to know about the schedule. You can try looking for the schedule and other significant information about the second year on the University or College or college's department website. You may ask your teachers or look at the academic calendar which must be there on the website. If you still don't manage to find details, then you may write in the comment section or you may repost your question with adequate details so that it can be answered accordingly.
