This is a great topic! I always like to read others’ journey and see how similar/different it is from my own. As for my own journey:
2013: Came across JapanesePod101 and thought that the idea of learning Japanese was cool. So I signed up for it, watched a couple of videos but never got any interest going so I stopped soon after.
2015/6: In my 2nd/3rd year of uni, I got to know about my uni’s exchange program and came across a prospectus of Waseda University. It looked gorgeous and kinda got me interested to study there/Japan one day.
2017: Maintained my grades well and got offered for the exchange program in my final semester but there was no Japanese uni offered that year (
) and chose South Korea instead (still a good experience!).
2019: Early in the year I got to know about MEXT scholarship. Researched a lot more about it, went to a briefing and decided to apply it. This is also where I decided to start learning Japanese again while waiting for the result. Started with Hiragana/Katakana by watching JapanesePod101 and other youtube videos. Also started using Duolingo and other apps like Anki, Drops etc.
2020: COVID happened. Dropped Duolingo because I lost the streak in a really busy period. I didn’t feel good about paying to ‘recover’ the streak because of my own discpline (I think I was being too hard on myself but also glad that I stopped Duolingo). Started researching about other ways to learn and decided upond enrolling in a local language school for 8 months. However, it turned out to be not worth the money I paid because by the time the classes ended, I felt like I was barely N5 and could’ve also saved money and learned whatever I learned by myself (Still had fun and made some friends though!)
2021: Still in COVID era. Stopped learning Japanese altogether in order to focus on what I was pursuing at that time.
2022 Jan-July: COVID restrictions finally eased and JLPT exams starts to be offered again in Malaysia. Immediately registered for July’s N5 exam despite not studying regularly. 2 weeks before the exam, started to feel the pressure and only did Hiragana/Katakana practice using realkana (similar to GoKana) and kanji/vocab practice using its kanji counterpart, realkanji. Passed N5!
2022 Aug-Dec: Similarly, registered for N4 and barely studied. Did the same practice + only learned 2 grammar points before the exam: ~ように and ~ために (I think I came across this a lot in mock tests and always got confused so just decided to learn these 2). Passed N4!
2023: When taking my N4, I realized that I could no longer just rely on my vocab/kanji practice and not learn grammar as I noticed the reading part got harder for me because I did not know a lot of grammar. This was the time I decided to actually learn and focus more on grammar. Researched and tried around a few apps and came across my savior, Bunpro! What I loved about Bunpro was that every grammar point was listed by JLPT levels, making it really easy for me to structure my grammar studies and schedule how many I should learn per day as opposed to other apps/sites where they are grouped by similarities rather than JLPT levels. And as I only have enough money to subscribe for around ~1 year, I planned my studies accordingly to this constraint I have. I learned 3-5 grammar points per day until I finished that level, took a month break before starting a new level. All in all, I managed to finished everything around ~11 months, which is just within the timeframe I wanted to and continued taking JLPT every 6 months when possible. Just to sum up, my JLPT journey was as follows:
July 22: N5 passed! 
Dec 22: N4 passed! 
July 23: N3 passed! 
Dec 23: N2 failed!
(found out my reading was bad!)
July 24: N2 passed! 
Honestly, I owe a lot to Bunpro for making it easy to learn grammar as it was my crutch for the longest time. Used to hate learning grammar and just stuck with learning vocab/kanji because I was good at that and didn’t want to leave my comfort zone but Bunpro changed that! (I still have a lot to learn though, learning Japanese never stops!
)
For JLPT N1, highly likely taking it this July, expecting to fail and retake it Dec
My problem currently is that I can read and listen but my comprehension is lagging a lot behind. So by the time I finished reading a sentence/paragraph or listened to a convo, I lost track of what I read/listened to, which cost me a lot of time during JLPT. So this is what I will be working on.
Seeing everyone work hard studying Japanese here makes me want to do the same!
