    Any guesses for boundaries???

    I really hope it is...
    A* = 71/100
    A = 65/100

    Although, I didn't find the paper as bad as I perceived it to be, I still got to admit that the format and everything was different. There are only a small minority on this thread. We may have all done well but the boundaries is based on the whole population. I just really hope that I wasn't the only one who didn't do as well as expected

    Usually, I finish this exams in an hour and a half. No joke that last trace took me like 45 minutes cause I had to keep starting again.
    Hah I spent like half an hour on it just getting confused then took an educated guess, never seen an algorithm that confusing before.

    Where is this A*- 71 coming from? Hate to break it to you but I think they'll keep it in the same area as the previous 2 papers which were 79 and 80 for an A*, maybe slightly slightly lower, but then that's my own opinion as I didn't find it too difficult.

    I second that. Its an easy algorithm when I see other pseudo code but that one with the daunting table I just got lost and got stuck in my own infinite loop of losing track ha.

    Should have been two "one to many" relationships.
    Incorrect it said that there was only one book. One one to many and then a one to one

    I disagree - I think it's 2 one-to-manys.

    The same book can be loaned lots of different times so can appear in the loans relation lots of times and a member can borrow lots of books. The primary key for loans was bookid + MemberID + DateLoaned.

    SageDerby, youre right. Its two one to many relationships, and I will explain why.

    For my coursework, I implemented a stock control system which required a database backend.
    For my analysis section there was a many to many relationship between stock and product. However, a many to many relationship cannot be implemented in any database, and so a third entity needs to be introduced. To esthablish a connection between the entities two one to many relationships will be needed. I know this very well, because my teacher explained the whole concept to me about three times , due to its importance. Luckily, I never truanted any of his lessons .

    I just felt that AQA really helped us there by introducing that 3rd entity for us . Hope that helps .

    Fair enough mate. What do you reckon the grade boundaries are going to be?

    After second thoughts, I think the boundaries for a...
    A* = 77/100
    A = 67/100

    Thats just my opinion. Although, I may have not found this paper as hard, I still felt that there are sections where candidates could easily lose marks. I think there are even some questions that candidates must have done badly in some topic questions such as the hashing; depth first traversal; OOP classes; and maybe some definitions.

    Those grade boundaries seem very reasonable, I'd agree with that, I think A* will be in the region 75-80, and you've put it more or less in the middle. All we can do now is wait until the 16th of august as AQA release grade boundaries on the same day as results.

    Thats true. All I saying is that I will be SO happy if the boundaries for an A are like 65/100 for an A.

    Sorry to be such a pain, but has anyone got a copy of this paper? Just want to have a look at it.

    True but I feel aqa never really apply their questions to the real world. In the many databases I have created you would create tables to store the historical data. So once a book has been loaned it is then moved into the respective historical tables. I agree in their question it will of created a link table but in fact this is an inappropriate way of doing so.

    Foolscap, I really do hope my predictions are right. Because some of the topics I was predicting to come up, came up . If you see my posts before the actual exam, I was predicting tree traversals, thin vs thick networks, asymmetric encryption and hashing. You can check my posts on this thread before the exam took place.

    Although no-one knows the official boundaries, I strongly believe that the boundaries for an A will be less than 70, and more than or equal to 65.

    Yes, there were some easy gainers such as BNF, Regex, FSM and Real. However, there were some harder questions that candidates may have suffered on such as tree traversal, hashing, and maybe networks.

    Don't worry man, if you got more exams (like me) worry about those. If you have not go party. I have realised its only a grade on a piece of paper, don't kill yourself try your best. I am sure you did so just wait
