Aayushi,
A First-year engineering subject student studies subjects related to all streams like Engineering drawing, Information technology (computer programming), environmental science (ecology), electronics, basic of civil engineering, applied mechanics etc. This is purposely taught so that student is well aware of basic terms/ fundamental of other engineering branch. In real life, oftenly, no particular engineering team works alone instead they work as a team. For example: A CSE student studies electronics fundamental so that later in his/her career one is capable enough to work with team of electronics engineers and can easily understand the terms of the electronics working of the computer to make better applications and devices.
Similarly, in future if a structure (for example: a building) is to be constructed, then it needs assistance of a civil engineer, electrical, mechanical engineer, architecture, may be more sometimes. A Team works better if they understand each other language (fundamentals) easily!
one should take 1st year subjects seriously, as they are easy to score as well.
I hope this was helpful!
All the best!
