The primary selling point of the Jahshan Reading Repack is . Jahshan’s Part A texts are intentionally dense. The vocabulary is more academic. The sentence structures are more convoluted. The "distractors" (wrong answers) are much closer to the correct answer than in the official OET book.
However, if you are a native English speaker or a highly proficient non-native speaker (C1 level), you do not need the Repack. Standard OET preparation books (like Practice Tests for OET by Ros Wright) will suffice.
For the dedicated nurse or doctor who wants to guarantee a pass, the Jahshan OET Reading Repack is one of the most powerful, challenging, and effective tools on the market. Just remember: the exam is a test of English for healthcare, not a test of how well you can survive Mr. Jahshan’s tricks.
