Recently I have found an easy way to earn 200 A-spec points in Arcade Mode. First you take a F1 car to a track (any track). Raise the difficulty to +1. Before you start to race go to setting, drop the power to -20% (713 hps), also add weights by +3% (566kg). Then change the tire type to RM, and TCS and ASM will not effect A-specs. Start the race, you should be racing against other F1 cars. Should be an interesting F1 battle. Oh I always set lap time at 3 and no penality. Enjoy!!!
