The electromagnetic workbook recommended Zhang Zhixiang's solutions to thousands of electromagnetic problems. The textbook can be Zhao Kaihua's New Concept Physics and Electromagnetism. In addition, you can read Feynman's second book after class. Mechanics Look at Shu Yousheng's mechanics, and there are matching problem sets. Liang's is ok, but there is no problem set. After class, you can read Landau's first book (which is mainly analytical mechanics and also beneficial to general physical mechanics)
