I think they would sound natural to a BrE speaker. In AmE we would usually say "take a test" and "on the weekend".

Are the following two sentences grammatically correct? Also, do they sound natural to a native speaker?
1. Our classes are generally funny and relaxed, except when we have to write a test.
2. At the weekends I usually go to the beach or do some yoga.
In BrE most of us say '...except when we have a test', and 'At weekends' or 'At the weekend'.

Please note that a better title would have been Our classes are generally funny and relaxed.
