Hey,
So I’ve noticed that with certain grammar points, e.g. causative / passive causative, Bunpro only tests you on the conjugation of the verbs as opposed to the use of particles.
For example,
私は 友達に 宿題を手伝わされました
友達は私に 宿題を手伝わせました
Although these two sentences are similar, they have two different meanings. Yes, the difference can be understood by the change in verb conjugation. However, the following sentences have a completely different meaning based on the small change in particles.
友達は私に 宿題を手伝わされました
私は友達に 宿題を手伝わせました
Does anyone else feel that they would benefit from being tested on particle use also?
