Hello,

Could you please tell us what degree you're pursuing currently and in which semester you're in?

Comment below your answer for the above question and we will get back to you soon with possible ways for self learning the incompleted portion of syllabus.

Although I can write down few tips :

Take each incompleted topic and search in YouTube, you will find many YouTube videos, so you can learn from those videos.

In either way, type the topic name followed by notes in Google Search, you will get many website links related to the topics.
