Gradient is the difference on the y axis divided by the difference on the x. (If it was calculating the gradient between points (2,4) and (3,6) the calculation would be 6-4 / 3-2 = 2 which would be the gradient). Tangents could come up if rate of reaction was tested.

If you show me an example question I can help you. I understand the stress of GCSEs having been through them myself. Biology was my first exam last year and the hardest but I’m sure you will’ve done better than you expected. Look forward and try not to be put off 😊
