Since you also used Level Up this year so you are in a better position to understand and compare.
Based on outstanding Marc’s introductory videos (available on this Forum) along with past charterholder’s comments on the quality of LevelUp, I went for Marc’s videos very early. However when I started listening videos, I realized that although Marc go through the entire curriculum, but something was missing for me to understand the topics properly necessary to correctly attempt the exam. I can’t explain the confusion but for me the videos were only the extended version of any bootcamp where people basically revise things quickly but may not be used by someone who wants to have a very good grip of the topic. I mean I could have read the curriculum by myself and reach to at least the same level of understanding which was attained after listening to the videos. But I knew the understanding which CFA Level 3 requires was much more than that. Marc’s Slide Book was good but it only became the reference point for my own notes. Here I want to give the disclaimer that the above experience was of mine only and should not be generalized for any other person.
So having unsatisfied with LevelUp, I switched to IFT within 3 months and I never regretted this because in the end when I left the exam room, I knew I would pass. I took IFT’s Basic Plus package i.e. everything (Notes, Videos, Summaries, Past Paper Solution etc) except for question and answer with the teacher and grading services.
Now there is a huge difference between Marc’s style explaining topics and solving BB and IFT’s style. Marc explains you what is in the BB (in most cases) in his own words but I was looking to fully understand what is written in the explanation of the curriculum.
However IFT solves almost every BB from reading every line of question along with highlighting and identifying key information in the question so that you can follow the same approach in the exam and then solve the question in the logical manner using the similar explanation as provided in the curriculum with more emphasis on the points which are hard to understand.
Finally his solutions of past paper gave me confidence as how to answer and how much to write during last month before exam. He uses same methodology of solving past papers as he utilizes to solve BB as I explained above i.e. reading every line of question, highlighting key information and solve.
You can also follow his notes and I believe his notes are also very good becasue these are also strictly from Curriculum. Nevertheless I used his notes, curriculum and Marc Slides to create my own notes. The benefit of which was I revised the entire curriculum at least 6 times before the exam.
The only thing which I am not sure about is his grading service. From the comments found in the forum Grading Services is best of MM. I wont recommend you to take IFT grading service. If you need one to be doubly sure to perform better in the exam then you must have known about MM or may consult S2000Magician.
Don’t hesitate to ask me anything should you require any clarification.
