You should only have one window openthe one you are taking notes in. Close all other windows and programs. Consider turning WiFi off. Put your phone away. Pick a note-taking or word-processing program that works best for your needs. For example, you may want to pick a program you know well, like Microsoft Word. On the other hand, you may want something simple and basic, like Text Edit. Consider using a note-taking program like Evernote or One Note. There are a variety of keyboard shortcuts that can help you take notes more quickly. Keyboard shortcuts can vary depending on the kind of computer you use (Mac or Windows) and what kind of word-processing program you are using. That being said, you will find keyboard shortcuts useful for the following note-taking issues: Formatting. Keyboard shortcuts can allow you to emphasize key concepts through shortcuts that help you highlight, bold, or underline words or phrases. For example, command + B will make a word bold. Navigation. Certain keystrokes can help you move to the beginning or the end of a line. Other keystrokes allow you to move seamlessly between programs or windows. In the Windows program OneNote, using the "End" or "Home" key will allow you to move your cursor to the end or beginning of the line you are on. Organization. Keyboard shortcuts can allow you to automatically make ordered, hierarchical lists like outlines or numbered lists. Type expanding. You can program your word processor to recognize phrases as you type them. Instead of typing out "interdisciplinary coordinated calculus" you can type "icc" and your computer will know what you mean. Writing down everything the teacher says will waste time. Instead, pick up on larger, overarching issues. You should be writing out short sentences, no more than five words. You can always come back to a concept or ask a question. But don't spend time finishing up a section to your satisfaction while your professor moves on. Instead, switch concepts when they do. After the lecture or class is over, go over your quickly written notes and fill in any gaps. Take this time to Add any information you were not able to type quickly enough. Fix any typos or misspelled words. Pick up on larger overarching concepts and add them while they are still fresh in your mind.

summary: Limit distractions. Use an appropriate program. Learn keyboard shortcuts. Listen for key concepts, don't transcribe. Move on when the professor moves on. Revisit your notes.

Double-click the Excel document that you want to edit. Doing so opens it in Excel. In order to include all of the cells in the longest column, you'll need to know to which row the column extends. For example, if you have three columns and the longest one has values from row 1 through row 20, your formula will need to include rows 1 through 20 for each column you want to add even if this includes blank cells. If you're adding the A column and the B column, for example, your beginning column is the A column and your ending column is the B column. Click the cell in which you want to display the sum of your columns. Type =SUM( ) into the cell. In the parentheses, type in the beginning column's top cell number, type a colon, and type in the ending column's letter along with the longest column's ending row. For example, if you're adding columns A, B, and C, and your longest column stretches to row 20, you would enter the following: =SUM(A1:C20) Doing so will display the sum of all of the columns in your selected cell.
summary: Open your Excel document. Determine which of your columns is the longest. Determine your beginning and ending columns. Select a blank cell. Enter the "SUM" command. Enter the cell range. Press Enter.
