Slow progress!
We did not want to take up any important space in the forum for this thread, so we decided to post it here.
In a different thread we found out that our math background is very deficient. For the last few days we have been using Khan Academy to fix the gaps in our education. After taking an aptitude test, Khan Academy started us at the very bottom, in 4th grade math. It took us 10 hours and 51 minutes of work to pass 4th grade math! It was a lot harder than we expected! As we pass milestones and things like that we will post our progress here. Khan Academy is set up with all sorts of crazy reporting tools, so if you want to see what we have been working on, and for how long, and where we are having issues, just create your own Khan Academy account and send us a PM and we will set you up with "coach" access to our account. We hope to have 5th grade knocked out in a few days. They do not let you test on stuff you just learned or practiced. Instead, you have to wait about a day for the test to appear. This is supposed to increase longterm learning. Attached is our 4th grade chart. In the reports that are generated you can mouse over each block to see what the topic is.

If you want to get through it quicker then do mastery tests for each of the math missions. Much of 4th grade is a subset of 5th grade for example.
Currently I in the world of maths I am: 39 mastered, 27 level 2, 44 level 1, 18 practiced and 489 needing practice.

I made a profile on Khan Academy for shits and giggles. Frankly it seemed REALLY odd that the site told you that you needed practice in over 400 topics. I asked myself what 400 topics could it cover that Xyzzy doesn't know anything about?
As it happens, their initial aptitude test is REALLY, REALLY bad. They need more sample questions from different areas. Frankly, the questions should just keep coming and coming and coming and increasing in difficulty until too many mistakes are made. I know I got all the initial questions correct because they were very, very easy for a finalyear engineering student, and my results were just as "bad" as yours. I had "only practiced" singledigit addition. Huh? How did I even get to solving a single equation for x if I couldn't mentally add 19 and 6? Anyway, unless I am missing something, it's going to consume months to even see where I rate according to KA, because I need to wait 16 hours to see if I'm a master of the very first topic.

This is a waste of time. You need to study books or make some courses at your local university.

I am with you Mike. Sometimes it is heartbreaking how slow one's progress can be at times. I feel frustrated with my, ever more slowing progress, every day...

Yeah I thought I'd be able to get an accurate assessment but I didn't. I've already given up.

Most resources in this area at Leiden are (inevitably) in Dutch.
From Warwick, the following is (IMHO) a good attempt to expound what students should learn (or revise) first in mathematics at a mature level: http://homepages.warwick.ac.uk/~masb...oundations.pdf
