I have nejat, he said he posts his lecture slides but was the textbook useful or are his notes (along with practice questions) sufficient enough to do well in the course?

I didn't buy the textbook and I did really well in that class.

However, most of that class was basically review for me anyway.

I bought the textbook last year and rarely used it. He mainly tests from the lecture notes. The only times I used the textbook was to do additional practice problems and sometimes the LONCAPA questions were almost the exact same as a question in the textbook.
