No, there isn't any written exam for Engineering Drawing at the end of the semester exam. Yet, there may be a class test. The number of questions may vary but the questions won't be difficult and the examination is usually three hours. There would be three questions, out of which the students are required to answer any two.
After the class test, you may have to perform a viva-voce. A very limited time will be given to you to roughly draw whatever the professors say but it all depends on the professors who take the class. There may be only a class test, or only a viva-voce, or maybe nothing at all.
The important thing is that you have to complete all the plates or at least try to finish 90% and all the home assignments. If the students do that then the class test will go well for you. The viva-voce doesn't hold many marks. Also, try to be present in every ED class. Otherwise, you may not be able to finish.
