From my experience with immigrant students I know that difficulties with Algebra are caused by a weak foundation in Arithmetic; specifically, fractions and division. And difficulties with fractions and division are rooted in weak multiplication skills. A student that makes a 100 on the Khan Academy 4th Level End of Course will cruise to a B in Algebra because they can SEE the values changing in a function without constantly referring to the calculator.
To take my own advice, I started in K (Khan Academy) and have worked thru 77% of Algebra 2 with incidental work in Trig, etc. in 3 years; this was done with breaks as long as 6 months between sessions and progress really slowed down during Algebra 2. I wasn't obsessed with the project but I did work all the problems. It was humbling to see how awful my test taking skill had become but I learned the connections between Arithmetic and higher math content.
For study habits, I refer students to What Smart Students Know. I have a 1-page synopsis that I send to all my students.
For Reading/English work, I use the First and Last technique and Teach to Learn regimen.
I only work with people who want to actually learn (for whatever reason). I'm not going to do your homework for you.
