Copy a range based on a cell value

[tuke016]

I have a spreadsheet that I am trying to copy a range within a row to another sheet based on its value

I dump data into the spreadsheet from A to L. I assign the values below based on a lookup table in M.
Values
A+, A, B+, B, C, D, F, U

Now I want to copy the range A2:L2 to a different sheet based on its grade, i.e A+ goes to the A+ sheet, A goes to the A sheet and so on. There are approxamatley 4000+ rows in this sheet.

I have attached a small portion of the records.

Any help would be appreaciated, thanks in advance
