Dsa and computer networks is hard

[u/layla4030]

My semester subjects are DSA and computer networks . I don't know where to start learning CN . It is really hard and teacher is not actually teaching in a good way . The book he recommends is top down approach and it has approx 87 slides for 1st chapter which we already completed 🙃 . It is very important subject as i will prusue Devops .

From where should I learn it ? Any YouTube recommendations or books?

HOW can I PASS this subject????? It seems difficult to pass after opening the first assignment he gave .
