The link http://www.kevinackerman.com/study-notes-exam-252.pdf just mentions on a high level about various concepts covered in the exam there is no detailed explanation regarding them. Is it a good idea to start with these notes first? Or maybe just start with something detailed and then go through the kevinackerman notes?
Also its been so long since the last post here, is there any updated documentation on the 253 exam? Or any new approaches towards studying for this exam?
