Fifty cards, each with the phrase, a precise definition, an example sentence, and on the back the three things that actually decide whether you can use it: its register, where it sits in the sentence, and the closest alternative. In light of, for instance, is formal, opens the sentence, takes a noun phrase after it, and is close to given.

Ten markers to match with the job each one does: assuming that marks a condition, as a consequence marks a result, conversely marks a contrast, admittedly marks a concession, needless to say marks emphasis. Sorting by function is how you find the right marker while you are writing.

A mix of multiple choice and fill-in-the-blank, with an explanation after every answer, right or wrong. Your best score is saved automatically.

Some markers open a sentence, some sit in the middle, and a few are almost always last. All things considered normally comes at the end; in light of opens and needs a noun phrase after it. A correct marker in the wrong position is the most common C1 error with these.

By and large, on balance and all things considered mean almost the same thing but do not belong in the same texts. Each card names the register it belongs to, and that is what makes a real choice between them possible.

Concession, contrast, result, condition, sequence, emphasis. Grouped by function, fifty separate phrases become six small sets you can actually choose from mid-sentence, which is the only way they get used in real writing.

After you finish the flashcard deck, it automatically rebuilds itself from just the words marked “still learning.” A short second pass on the hard ones is worth more than repeating the whole deck.

Take a paragraph of your own writing and replace two ordinary joins — but, so, also — with markers from this deck. Then read it out loud: if it now sounds heavy, the register is wrong, and noticing that is exactly the judgment this module trains.
