Test Preparation Resources

Greetings,

I’m an emerging sophomore studying algebra 2/trigonometry over the summer. Thus far, it has taken me around 30 days, with 4-6 hours of routine worktime, to finish covering all the content in my school’s textbook. I am not studying to receive credit for my school’s algebra 3/4 class, but rather, to skip it entirely.

At this point, I’m just confused as to which direction I should take my studying. Are there any good test preparation or review resources you know of? I’m looking for ways to prepare for the class entrance exam, and any feedback is appreciated. Thanks!
