There are a few possible outcomes of this. These will come with many advantages and let me discuss them below with you:
Advantages in your course curriculum: There are very less instances where this might happen as subjects are taught extremely well, right from the basics. For example, classes like operation research, statistics for management courses.
Advantage during placements: In this case, both parties are of the opinion that the other is better off. But you should know that this is completely up to you and placement reports are usually a good mix of freshers and experienced students.
As a fresher, you might face a few challenges in the first month or two. But, be patient. This does not put you at a disadvantage for the next two years. Everyone gets an equal opportunity so there is no advantage or disadvantage as such.
