I recently finished Level 2 of Rocket Spanish and just started with Level 3. Lessons 15.1 as well as the 2 language & culture lessons 15.6 and 15.7 which I did were all fine. Then I got to lesson 15.2 and it's just so tough! The list of vocab on the exercises is very long (100!), the sentences are quite complex, and in some cases the speaker speaks really really fast!
In Level 2 I would go through the Hear It Say It and Write It exercises maybe 2 or 3 times (as in, once the whole thing, then another 1-2 times repeating only the items I didn't score as good), then the Flashcards maybe twice, and then the Know It once, and I'd be done. I don't remember exactly when I started, but I think it took me about 5-6 months to finish level 2, putting in time pretty much every day.
For lesson 15.2, I've gone through Hear It Say It and Write It maybe 5 or 6 times each by now, and still have dozens of items that I've not yet scored good. And even the ones that I score good, I struggle with them on the flashcards. I like a challenge, but I also like to feel like I'm making progress, and this is just overwhelming me!
I know I could just keep going and figure out the answer myself, but I am curious from someone else who has already gotten further than me: is the rest of level 3 like this? Or is it just some isolated lessons like the one I'm doing now? Cheers!
