How long will it take to complete al courses ranging from algebra 1 to calculus 1?

It is hard to say because not everyone works at the same rate.  The way I see it you want to complete about 5 courses: Algebra 1, Geometry, Algebra 2 (or Integrated Math 1, 2 and 3), Trigonometry, and PreCalculus.  I would look at each course, count the total number of units, and divide by the number of weeks (or days) you plan to dedicate to study.  Then attempt to complete the number of units per day and see whether that will work for you.
