Most spaced repetition software (SRS) programs are modeled after the manual style of learning with flashcards : items to memorize are entered into the program as question-answer pairs. When a pair is due to be reviewed, the question is displayed on screen, and the user must attempt to answer. After answering, the user manually reveals the answer and then tells the program (subjectively) how difficult answering was. The program schedules pairs based on spaced repetition algorithms. Without a program, the user has to schedule flashcards ; this is time-intensive and limits users to simple algorithms like the Leitner system . 
Dear Pamela,As a Brit, it’s nice to see someone from ‘over the pond’ who’s got most of the information about Afternoon Tea correct for a change: I now live in Vinci, Italy (yes where Leonardo was born), and now offer afternoon tea to Italians in our home dining would take you to task on one item in your article,(there’s always a critic!) and that is about Cream Tea in which you say: “Cream Tea — A simple tea service consisting of scones, clotted cream, marmalade or lemon curd and tea.” Cream Tea traditionally consists of scones served with clotted cream and strawberry said that if people prefer to have their scones (and it’s pronounced ‘skons’ as far as I’m concerned),with an alternative, I have no problem with that, it’s a free world (supposedly)!For example I sometimes fill my Victoria Sponge with lemon curd instead of the traditional raspberry jam and fresh raspberries both of which balance well with a nice cup of sweet Luck with the book!
