In first year I bought almost all my textbooks.
In second year I bought maybe a quarter of my textbooks.
In third and fourth year I bought one textbook.
I noticed as I went through my engineering degree I never really used my textbook at all. Most of the information I needed I could find online or I could just find a digital copy of the textbook online. I also found reading the textbook was not helpful in preparing me for exams. I found that doing more practice problems was what benefited me the most in succeeding in my midterms and finals.
One thing I thought that was pretty ridiculous was the price of the textbook! Some of the text books the professors wanted us to buy could range either from $80 to $300. I remember buying a textbook in second year that was worth close to $200 I believe. It was a microelectronics by Sedra Smith. I did not use that textbook at all. However, there are times when I did use the textbooks quite often.
In fourth year I bought a textbook for my Semiconductors course. I found this course really interesting and I usually don't enjoy reading things off a computer. So I ended up buying it ($80 I think). I didn't read the textbook as often as I would have liked, but when it came to exam time and midterms I would read the textbook like crazy!
I love how one or two hours before the final exam people read their textbook for the first time and try to learn 100's of pages worth of information. I wonder how much information they actually retain haha.
Another thing I hated was authors who changed the edition of their textbooks. I'm pretty sure they just used a random number generator to randomize their textbook questions and maybe added one or two pages to their textbook to change the page numbers. I'm glad some of my professors said it was okay to use old textbooks. If you plan on buying textbooks try to buy used ones!
Here's a question for the readers. Do you buy your textbooks? Or do you usually find a digital copy or find the information you need online? Also what was the most expensive textbook you have bought?
