I am going through NPCR on self study.
Should I add words for a chapter in Skritter, study them and then read the chapter or vice versa?
Also why does skritter keep holding on to words I have added for hours. For example few words I added two days back don't show up for study. Isn't it strange?
I am manually adding words.
Also in case i manually add words does Skritter try to achieve retention level(I have set mine to 87%)?
