The next topic will be updated soon. You can send the question bank related to chemical engineering software (along with answers) to my email at 12315827@qq.com. Once it is included, a reward of 10–100 wealth points will be given depending on the quality and quantity of the questions. If you have a large number of questions, you can contact me via the in-site messaging system; rewards will be provided collectively, and they are not limited to wealth points only. The question bank will serve as the source for the “One Question per Day” section in the chemical engineering software category. First come, first served – rewards will be granted based on the first email received. Please include the forum username and UID in the email subject.
