Don't remember exactly, but i try...
After the intro, go buy chocolate (to have it for the next day for Rachel) and then go to Rachel's house in watch the scene. Next day, in school, go to Rachel, speak with her two times and give her the chocolate, then, after exiting the school call her on a date to start Maria's quest. Some period of time you will not have access to school so, first, do your chores Maria gave you and then you can work at Amaria's bakery, start Sarah's quest, upgrade your computer with the money earned (i don't like cheats and you need it for Jet training), also in the weekend you can give the second card to Sarah and find suspicious packages. When you start having access to school go directly to Rachel so you can start Miss Taylor quest and give the third card to Sarah and after that go to Rachel's house immediately and every chance you get (weekend morning, afternoon) until you need sex education with Jet. After giving the third card to Sarah continue to the forth one in the comics store and finish the quest (for jet first quest). Also, insist on Jet training when possible to finish it as fast as you can so you can do the first quest until Dad arrives and buy some rope in your spare time not to lose another day on it. In recess it's your choice, i opted for Daisy and Beth and you can finish both in exact time until father arrives. Don't forget about Maria and her chores...
