Simplify the schematic and layout as much as possible for initial testing. Fine-tuning, zeroing, and additional stages can easily be added after you have the basic circuit working.

Be sure to include IC number, package type suffix, and pin numbers on each IC on the schematic diagram.

Make the layout look as much as possible like the schematic. Refer to the schematic whenever you debug your circuit. 

Locate input and feedback resistors as physically close to the IC as possible. Long leads, connecting to remotely located resistors, pick up noise. This noise is then coupled to the highly sensitive input pin of the IC. 

Keep the inputs well separated from the outputs to prevent oscillations.
