<p>That drill isn’t meant to be kick-your-butt hard, it’s just meant to throw a bunch of common question types your way. If you got any wrong, then there’s a common question type that you’ll likely see again that you should be reviewing.</p>
<p>I say it’s not meant to be done in 25 minutes because it’s, on average, full of tougher questions than an SAT section. A real SAT 20 Q section will have a couple very tough ones, a bunch of easy ones, and some medium ones. My 20 Qs have no really easy ones, a bunch more medium ones, and one or two tougher ones. In other words, if you usually finish SAT sections with time to spare, you’ll probably do the same here. But you shouldn’t judge this as an SAT section, you should just use it as a tool to discover if you have any glaring weaknesses. The other drills on my site have the same purpose.</p>
