Step 1 – Soldering Resistors.

There are 13 resistors to be placed:

Solder the 4.7KΩ  resistors (7 units): R3, R4, R6, R9, R10, R12, R13.

Solder the 100KΩ  resistors (3 units): R5, R7, R8.

Solder the 1M resistors (2 units): R1, R2.

Solder the 1.2M resistor: R11.

tips: 

- In order to solder the components, bend the leads close to the

body, introduce them in the footprint and once soldered cut the
excess of lead as short as possible to avoid short circuits.

There is a  

nice video on Youtube

  to learn how to solder from

scratch.
