The subjects may differ from university to university. As you haven't provided your university it difficult to provide it to you.

In most of the universities in the 1st year 1st sem two subjects are found that are Introduction to Microbiology and Microbial Diversity & Bacteriology . In the second semester most of the universities offers courses of Biochemistry & Cell Biology.

This are the subjects you may get in your first year. Also it may differ according to your university.

I hope this answer helps. All the very best for your future endeavors!
