The practice test will allow candidates to take an operation demonstration test project.
General inspection in practice: calibration of calcium, phosphorus, hydrochloric acid, urease activity, crude protein, etc.
The inspection of crude protein, the final titration step of general inspection, and the previous digestion test can not be inspected on the spot because of the long time.
In the calcium and phosphorus exam, the teacher will prepare the computer or titration solution in advance. You need to do the following steps.
And generally you will be allowed to operate while reading.
The actual exercise time is more flexible, and you will usually leave after you finish. There is a practice sheet on which you need to record the process.
Remember to be parallel. The calculation results should be average and relative deviation.
If you need to use the instrument, the teacher will take you there and tell you how to use it.

The teacher mainly examines your practical ability and common sense.
For example, you must know the most basic sampling, the use of burette and beaker.
