First action: pick one small group of about five prepositions and put each in a short sentence you actually use. Write them on a card or in a note today. Study the group for two or three minutes, then set it aside until tomorrow.
Your practice loop
Review yesterday's group from memory first. Say each preposition with its sentence aloud, then check your note and add a mark beside any one you missed.
Add about five new prepositions the same way, each in a sentence from your own life. Keep the new set on its own card so groups stay small and separate.
Turn any missed prepositions into tiny cards, one side the sentence with a gap, the other side the preposition. Keep lists and explanations on different cards rather than cramming everything onto one.
Schedule spaced reviews for each group on days 2, 3, 5, and 7 after first study. Treat this as a framework, and stretch the gaps if the material feels easy or your pace demands it.
Set a fixed daily slot, even five minutes. Spaced review only works if it happens most days, because skipped sessions let missed cards pile up and reviews become a chore.
One complete demonstration
Here is one full run of the exercise with a five word group. Suppose your group is at, on, in, from, with. Write one real sentence for each, like I eat lunch at noon or She walked in with a smile from the bus stop. Keep each sentence true to your own day.
Say the group aloud twice: once the bare word, once the whole sentence. Then cover the note and write the five prepositions from memory, one per line, each followed by its sentence.
Uncover the note and compare. Suppose you wrote in correctly, but your recalled line She walked in with a smile was your memory of the sentence for from, She walked in with a smile from the bus stop, with the from part dropped. You paired one preposition's sentence with the wrong word, so mark that pair. Rewrite the missed one three times while saying it, then turn it into a tiny gap card: front She walked ___ with a smile, back in.
Total time: about three minutes. If every word was recalled cleanly, that is still a pass. Getting them all today does not mean they are settled yet. It is tomorrow's review, when you cover the note again and write the five from memory, that turns them into words you really know.
Self-check and next adjustment
After a few days, test each group of five. Cover your notes, write all five prepositions with their sentences, then count what you got right. Four of five means the group is nearly settled; two of five means it needs another day before you take on more.
When several groups have piled up, test them one at a time the same way, not the whole accumulated set at once, so a weak group cannot hide among strong ones.
Do not worry if recall is shaky. Struggling to pull something up a little late can strengthen memory more than reviewing while it still feels easy. That wobble is a normal part of the routine, not a sign the method is failing.
Judge progress by recall quality, not by how many times you have looked at the cards. A clean, effortless write out of a group today matters more than five quick glances yesterday. Slow, honest recalls are worth more than fast, prompted ones.
One adjustment: if a group passes two checks in a row with everything correct, stretch the gap before the next review. If a group keeps failing, bring its reviews closer and cut the group in half so it is easier to hold.
Whatever you change, change only one thing, then check again the same way tomorrow.
