I understand you very well. I had a similar situation. Only I was forced to read not 'Pride and Prejudice' but Charlotte Bronte's 'Jane Eyre'. I read about twenty pages and left it. I'm lucky that I found this source https://freebooksummary.com/category/jane-eyre and with its info I got to know the book. It helped me a lot in the exam. Now, whenever I don't want to read a book or don't have time, I do the same thing I did with jane eyre - a handy life hack, in my opinion. And for pleasure, I read Hemingway and Fitzgerald. 'The Great Gatsby' will forever be my favorite book.
