Hi,
I'm writing here seeking for help from the experienced and who already passed on this road. My goal is to understand daly life simple conversations, news and etc, so I firstly aimed at level N4

I have learned the 1-6 grade kanji (1006) the last month and now red once Tie Kim grammar basic and essential part.
While reading the Tie Kim/JtMW for a grammar I started with core step 1&2 (400 vocab).

My kanji remembering and grammar are ok, my biggest issue is when SRSing the vocab reading:

I can guess the meaning from the kanji but the reading just stick to my mind several seconds! Especially when they bombard me with several verbs or vocab that consist with few and similar syllables. Even the vocab is quite simple this homophonic thing drive me crazy and the reading just do not stick to my mind...

Am I doing something wrong ....any suggestion would help!

As you get deeper in, you start making associations and recognising patterns, and it gets much easier. It's like trying to memorize telephone numbers at first, though.

I recommend just using the sentence -> reading + meaning + picture + audio cards only, as the complete sentence gives you more exposure to the combinations, and more context to hook onto. Also provides kana practice.

Listening carefully to the sentence audio, replaying it a few times in your "mind's ear", and speaking it aloud provides some useful auditory context. Also studying the picture.

Anki's default settings for 'ease' and 'steps' are rather optimistic. I prefer to use something like ease = 150%, steps = 40 80 120 240 (similarly for 'lapses').

For difficult cards with long kun readings, try focusing on recalling just a single kana letter at first. I usually find the one nearest the okurigana is easiest. The remaining letters then become easier.

I found some visual imagery for some of the readings useful too. E.g. しゅう -> shoe. Doing RTK laid the groundwork for this.

I also used any lame coincidence in the sentence as a cue. E.g. if the target word starts with the same letter as another word in the sentence etc.
