S-1
Approach the hairpin corner from the far outside, reduce your speed shortly before reaching the left curb, and then steer sharply in. You'll have to reduce your speed at the chicane and steer in from the outside early on. Take your foot off the gas in order to re-ordinate your car aand leave the chicane as quickly as possible
S-3
Sections of this course will be familiar to you from previous tests. When taking tests B-8 and I-A2 you got to know the difficult section between the rock formation and the long tunnel, and you also dealt with the chicane at the end of the course. After the tunnel already mentioned, the last hurdle on this course is really the extended hairpin corner at the end of the long straight. Since the Mazda MX-5 is not known for its accelleration capabilities you should only take your foot off the gas when necessary. Especially on the incline following the extended hairpin corner you'll find that your car is struggling so take care to drive through the corner at top speed and make use of each millimetre to accellerate early on otherwise you will be crawling up the hill at a snails pace
thats it. i hope it helps you beat it but as i said i do not guarantee that it will work
