Yes, Activation chapter by chapter is perfectly acceptable. It has to meet your needs, your purpose so do it in a fashion that meets your requirements.
You'll find it more beneficial to go through a series of pages. It allows your inner mind to work on the preceding pages while you activate the next. Often you find upon returning that it is easier to understand.
Not going back is for regular reading usually the sentence if you have trouble comprehending a particular page try looking through the rest of the book or in the index to find out what other pages the subject/idea might be explained some more.
