Do you recall the Take a Test button? Once the user clicks that, I would like a small pop-up screen to emerge. The user then needs to choose firstly the product from some dropdown box option (Numerical/Verbal/Diagrammatic).
Once the user selects one of the product types, they then choose from another dropdown box immediately below; here they then choose the test version (Practice/1/2/3/4/5/6).
Once they've made both selections, the user then clicks 'Take Test'. This is the main CTA and so should be in keeping with the rest of the site, it should be the same orangey/yellow.
Note, if the user has not subscribed to the particular test version, it should be greyed out with the words 'Unsubcribed' next to it in brackets.
Note: 1 version of each of the three product types will always be available for people to practice. This is called the Practice test. There are another 6 versions of each of the product types.
Try to keep the colouring and styling consistent with the rest of the site.
This should be nothing too hard or fancy I think. I will have more work for you soon.
I've suggested $40AUD. Let me know if that's doable.
