Hi Beverley - sorry, I've only just seen this. I think we may have discussed this elsewhere in another thread, but just in case: there are conditions where Kwiziq scores can go down unexpectedly and we're aware that this can be very discouraging. I hope we can one day handle these conditions a little more transparently but a few things to bear in mind are:

1. The score is a measure of KwizBot's confidence in your knowledge, not the 'ground truth' about what you know. It's great to use it as a medium or long-term goal but don't take it too seriously over very short timescales such as each individual take. KwizBot's algorithms are complex, and he does have off moments too. If you consistently get things right then he will grade you higher over time for sure.

2. Negatives vs zeros: a zero score from a skipped answer can still contribute to an average dropping if it replaces an older score that was positive. A small drop in this instance is expected and still better than a much bigger drop that an incorrect answer would have resulted in. Once again, that little dip just means KwizBot lost a little confidence that you knew something which is normal if you skip answers. 

3. Aggregate scores for levels are calculated across the entire level(all topics and their constituents). We constantly improve and modify our content and so sometimes your aggregate scores can change without you doing anything at all. I'd love to make these events especially much clearer to users when they happen but just be aware it's possible. Again, focus on the longer game of scores over many kwizzes is the key to happiness, not each individual result.

4. A1 and A2 are definitely much harder to complete than B1 and B2. In fact, the levels contain almost twice the grammar content which you can see in the Brainmap view. There's a lot to learn at the start! Of course, grammar is just one view of a 'level', but that's what we're testing. C1 is tiny from a grammar perspective, but I'd say in reality C1 takes much longer to progress through in reality (and contains all the preceding levels, since they're 'additive') and C2, well, C2 never really ends... learning a language is a journey for life so make sure to enjoy it!

I just took a look at your achievements board. You've obviously been working very hard since you posted this! Well done. It's looking fantastic as is your Brainmap!

Courage et bonne continuation !
