Hello people, my name is Francisco.
I am a student that have been inactive for 2 years. Now, I would like to build a strong mathematics and physics base, would somebody tell me how would I take the most of this incredible tool called Khan Academy?
I'm just asking this because I've got some mathematics and physics knowledge, however, I have some "holes" in it. Would you recommend me to start from the beginning or it'd be waste of time?
Will I become a good user of these areas if I learn 100% of what is presented?
