First of all, they are serving for two different purposes. Assessment Test is for evaluation purpose, it is to test and assess your understanding and knowledge of the topics. Whereas Practice Test is for learning purpose.

Assessment Test does not give immediate feedback, meaning it does show you whether you are right or wrong when you attempt the question, instead it only show you the result at the very end.

Whereas in Practice Test, you are given immediate feedback once you have answered the question, you will know the answer and explanation immediately.

Assessment Tests are timed, and once stared there is a countdown timer, you are supposed to complete the test within the time frame. For practice test there is no timer.
