I took a look at your profile and I see that you have almost 500 apprentice items. That’s way too many. With that many apprentice items, you will get overwhelmed with reviews.
Your main goal should be to get your number of apprentice items down to a manageable number. For some that number is under 100, for some that number is under 150, you have to find out what works for you.
There are 2 ways you could go now. One way is to reset a few levels, down to a level that gives you a comfortable number of reviews, and then slowly add from there.
The other option is to use the reorder script and only do reviews from your lowest levels, let’s say level 1-5. Ignore level 6-20 and ignore your total number of reviews. Just concentrate on getting through your reviews from the lower levels and get them out of the apprentice queue. Remember that your goal is to get your number of apprentice items to a comfortable stage. Once you’re done with level 1-5, you can work on your reviews from level 6-10. Only those levels, ignore levels 11-20. Once your’re done with those and get your number of apprentice items down, you can do reviews on the higher levels. Rinse and repeat until your apprentice level is where you would like it to be and until you can go through what’s left in your queue.
And DO NOT add any more lessons for now. Just don’t. Not until your number of apprentice items is down where it should be. And from now on, never ever ever add lessons when you have pending reviews. And never add lessons when your number of apprentice items is too high. That will just dig you in deeper.
