1) I find it difficult to translate the following description into English since I don't know how old the students are in their fifth or sixth class. How old are the students attending the last two years of secondary school? In the US, most students in these last years of school are 17-18. Some are 16, but most are 17-18.

2) Can you briefly explain to me the difference between A level and ordinary level? What does it mean that they can study information technology at an ordinary level? I haven't heard of those terms. Can you give me more information? Which country? What schools?

3) When do they carry out group projects?

4) Why are the sentences "she admits she has fallen in love with Dorian/She admits being attrated to Dorian wrong?)
I don't see anything wrong with those sentences as you've written them here. Maybe in context there's a problem, but I don't know the context.

>>>spelling >>> attracted

Sure! Here are the explanations for each question:

1) To find out the age of the students in their fifth or sixth class, you would need more information. Usually, the fifth class corresponds to the age of 10-11 and the sixth class to the age of 11-12. However, this can vary depending on the country or educational system you are referring to. You could try to gather more specific information about the educational system in question to determine the age range for these classes.

2) A-levels and ordinary levels refer to different levels of education in some countries or educational systems. A-levels (Advanced Level) are usually taken by students between the ages of 16-18 and are considered more advanced and specialized subjects. On the other hand, ordinary levels are generally taken at a slightly lower academic level around the age of 14-16. Studying Information Technology at an ordinary level means that students can study this subject at a more introductory level rather than the advanced level offered by A-levels.

3) The timing of project work in groups can vary depending on the educational institution or specific course. It is best to consult the syllabus or guidelines of the particular course or subject you are referring to. Generally, project work in groups can be conducted during designated project periods or as part of the overall course assessment. It is important to follow the instructions and schedule provided by the teacher or course coordinator.

4) The sentences "she admits she has fallen in love with Dorian" and "she admits being attracted to Dorian" are grammatically correct, but there might be a difference in meaning and usage. "Admits she has fallen in love with Dorian" implies a confession or acknowledgment of romantic feelings, whereas "admits being attracted to Dorian" implies a confession or acknowledgment of feeling attracted to Dorian without explicitly stating love. The choice of sentence depends on the intended meaning and context of the situation.
