the Level 1 CFA curriculum _ I need your help

That’s a loaded question and depends on your style of Learning and experience. Kaplan is quite straightforward and to the point. CFAI material assumes you no nothing and will waffle on for a while. I found the CFAI books to be fine,but the topic quizzes they have online are very subpar. They may have only 50-60 questions for each topic quiz. It is good for an initial assessment, but if you redo the quiz, then you’ll get an over inflated score. You’ll only get two practice exams as well. They give you a full exam for 6 hrs with no way to pause for a break…a bit annoying. I found the Kaplan questions and exams to be better for review. kaplan will def get you over the line as well as IFT or ELan and now Passed Tense is coming up the ranks. Also, if you google this debate, you will get good responses on analyst forum and qora (something like that) as well. You can even YouTube them and they will give you over views too.

It is risky to not use the CFAI material. It is the source material and it is the most up to date – third party material can potentially miss the subtlety of changes that the CFAI puts in the curriculum. We recommend at very least reading the summaries and doing End of Chapter questions. 

That is one reason we do not have a separate 5 books of material you should read. We recommend integrating our material with studying the CFAI material. For example, Ben our resident exam passing expert wrote up a blog on it:

We have two full topics of videos available free on youtube if you want to check them out:

Kaplan is enought. But I recommend curriculum to everybody who likes to know what is actually happening behind all of these concepts (I dont like to learn more than I have to but in this case it worked for me) 

I read everything from curriculum once and highlighted the most important stuff. Then I read it for a second time and I copied highlighted stuff to my personal notes (1 page A4 of every topic, overall 60 pages of notes). After doing this I still had 1 month for practical questions, remembering the formulas(very important), and reading my notes.

The most important is to start early so u dont have any time pressure at the end. 

I haven’t used Kaplan curriculum, so cant comment on that. But I do use Finquiz which just summarizes/provides key notes. The official material is the bible/main source – all other aids are meant to enhance your learning. The notes/aids are helpful if you want to save time/energy, which is important as we have other engagements in life. 
All said and done the official material can’t be ignored. You can use the notes to skim through certain areas or to finish faster, but you have the risk of missing out the background material or how/why certain concepts exist. For people with previous finance/business background the notes might help them to skip the CFA materials and quickly get to the summary/questions. Its a kind of trade-off decision you need to carefully take.
