SOL -Bcom Pass 1yr paper date and doubt

I registered for bcom  pass 1st year in oct with sol/school of open learning, moti bagh/south campus

I checked their site it shows that some paper were in Nov/dec abd some in April, I am confused, I am think that I have to give paper in April, am I correct? or didI missed some papers?

Also it shows that Bcom and Bcom Pass (OLD course) - paper is on 13th April. How can i come to now if I am in new course or old course? I tried calling AOL, but they hardly answer questions on phone as they are very busy.

Further, it shows just one day for the paper, so it means I will have to give all 5 papers on a single day? Thats kinda difficult isnt it assuming one paper is of at least 1 to 2 hrs long.

And just studying the study material sent by SOL is enough? I checked and found that they didnt sent Business Studies book, so I assume Business Studies book is not provided by SOL and needs to be purchased from market?
