Done 4 HV/AP courses well 1 and 3 re certs. If this is your 1st course then you will be shown how to construct a switching schedule, different companies have differing ways although they will all be pretty much the same, they have probably given you a schedule to write to see how much you don't know about HV switch gear, How long is the course and who is it with? mine was all MOD at the training center ran by the PSA at RAF Cardington, sadly no more.
Looking at your profile you say you are an Engineer, what sort of Engineer? would that be something like a site Engineer on a large complex that has it's own HV system? the subject is to complex to advise you over the forum, my advice would be to go in cold, and assume you know nothing, start from scratch, oh not wanting to put a damper on things most of these courses are designed to certify you as an Authorised Person for your particular site, it's no a cake walk, plenty of exercises to do in the evening, either pass or fail.
