With the respect of the "effort" the author inputted, I bought a new Actex MLC manual with about $200. Not worthy at all! Almost a copy of the previous M, but more typing errors like, "this the ...", the question is about (40), but answer given is about (50)................. I found about 10 such errors in my glance at the first few modules.
Nothing is perfect, but this manual goes too far. The author should have respected his readers more.
