Q28: How do you divide the time among the various categories of experience?
You would have to estimate your various working experience in proportion to the work carried out. At the end of each 3 months, you have to summarise your work and provide a time estimate of your work in each category of experience.
Q29: A Graduate would have to send the log book to IEM for checking. How long does IEM take to return the book? What if it gets lost?
Perhaps you should send in by registered mail and keep photostat copies of the book in case it gets lost in the post.
