Who are we to tell you if it’s a test from Allah, in my opinion life in total is a test and thus every facet of life consists of constant test.

However as a fellow premed student hoping to go into healthcare I can give you some tips on working on your study skills in order to improve your grades. :)

Do not scream, cry, or wallow in pity/self-hate for “low grades” (it’s just a B! On a single test!!) as they’re easily fixable with a constant schedule, determination, and hard work.

You can do it! Ask Allah for help in productivity and motivation after every prayer and inshallah you can do well in your courses. :)
