Uncorrected Learner Example
Comments At A1, there are instances of 'if' + present, mostly with 'need' and 'want' but they are limited to a narrow range of L1s and many have errors. Most are suggestions and offers, e.g. 'If you need my help, you can call me.' There are examples of 'if' + present + 'will' at A2 but they are mostly limited to Romance L1s and very often not appropriate.
Note on punctuation: many grammar books stress that when the 'if' clause precedes the main clause, it must use a comma. We cannot establish a consistent competency for this (and punctuation in general). It seems too idiosyncratic. L1 can be a skewing factor.
