Many years ago, I took a Russian 101 level class in spring, then immediately went to Russia that summer. Glossing over how that was a horrible idea, I was faced with two options for class in Russia: repeat the absolute beginner class, or skip the 102 level class to join the second year. Being the ambitious person I was, I chose the second option, and regretted it the whole time I was there. The 102 class I'd skipped had some incredibly vital lessons, such as how to conjugate verbs and noun/adjective declension - things you were (obviously) expected to have mastered by level 2, where they piled on the vocab to fill in that framework. Without that base knowledge, I struggled a lot with new concepts and just generally had a horrible time.
Fast forward a lot, and now I'm learning Japanese just for funsies. A local community college offered levels 101 and 102, but nothing past that. I looked around a bit and found a regional society that offers many, many more levels of instruction and even uses the same textbook for beginning levels as the community college classes. Sounds great, right? Naturally, there's a catch... the community college covers four chapters in the book per class, while the regional society only covers three. So my options for moving forward are:
- Review two chapters I've already done and have one new chapter in level 3; or
- Skip one chapter and move ahead with all-new material in level 4.
