Poor grammar and typographical errors – Navigate TestPrep: EMS Review

I decided NOT to purchase additional questions after encountering several grammatical and typographical errors in the practice questions. It seems odd that an app connected to a textbook publisher failed to hire a proofreader. When developers try to charge $$$ for in-app purchases, they should strive to provide the user with a high quality product.
