Grammar app that needs a grammar check

Just got this and made it thru the noun section so far. Unfortunately numerous questions need to be scrubbed for grammar errors. (incorrect plurals, question mark at the end of a true/false statement, misspellings (firelighter instead of firefighter), etc.). Also, the reading material is missing content that is covered in the test questions, i.e. gerunds… I have a feeling there’s probably more because this reading material is very brief.

App could be much better after a thorough scrub. Not worth $20 as is.

Dis user hoped for more about Grammar Express - Super Edition
