I have never felt so supported! I thought I should expand on my answer a little. The method I was using with the spreadsheet was something which I stole from small white. Basically I found a bunch of words which were subject specific and then I put them into a spreadsheet. I used to have this available for download but can't find the link. If I find it then I'll edit this post. But actually it is easy to make your own. You put TL word or phrase in column A, then NL translation in column B. Then put conditional formatting on column C, such that if A ≠ B the format background colour to red. Then just hide column A, and type your answer in C. If you're not right it goes red.
You can do some excel wizardry to improve on this method, but it quickly shows you want you don't know, and you aren't limited to a number of reps per day.
I was doing this after finding a lot of subject specific words. I did a playlist on YouTube showing most of this.
https://youtube.com/playlist?list=PLIdb ... O1mbKIpLxLI'm on a tablet at the moment, so if that link doesn't work then I'll edit that later too.
So, I should point out that this cramming of 1500 words a day didn't last long. I think I only managed to do it for about 2 weeks consistently. However, I did load all those words into anki and I have been doing about 40-60 new cards per day, but when the reviews pile up to much I scale it back to only 5 new words per day until the reviews drop to a reasonable level.
My strategy at the moment is I have three decks with subject specific vocabulary. Food and D&D words and numbers up to 100. The numbers test audio first the other two are just basic word cards. I then have two decks which are phrases both with audio. These are my language learning decks, although I also have a couple of others for personal information, some math stuff, some inspirational quotes.
For me the maximum new word count with anki tends to be in the 40-60 range. More than that and I get too many reviews and it takes too long. Less than that and I whiz through too fast. A quick look at my stats shows I've studied 90% of 2017 (331 days out of 365) and I average 247 reviews per day which takes about thirty minutes per day. Mind you these stats include the non-language stuff, but the bulk of it is vocabulary.
I would also point out that this was running parallel with my reading of 75 books, so that re-enforced the are.
I hope that helps. Feel free to ask if you need more information,
