In terms of revision, at least for Oxford I wouldn't get caught up in learning hundreds of Formulas for the Maths and technical tests. You don't have a calculator, and expecting you learn the Sin / Cos tables is way beyond the scope of what they are looking at.
The Technical test is more looking at how you approach a problem. The best advice I can give is think how to logically follow problems through. Ie if you had a pile of parts how would you construct them to solve a given problem. The rest is really basic.
90% of the score you are going to get is based upon your natural aptitude, only 10% you can revise for. Like the Maths test, you need to be able to read the question, compute the answer and type in the result in 50 seconds! If your not a natural at maths, that is going to be difficult. Remember that each FTO is going to only going to take the top 5-10%? through to the next round, so you can't afford any weaknesses.
Best of luck.
