Intelligence effects very much on learning, if subject/ individual has maximum level of intelligence he can learn more and easily at maximum level.
Attention is also very important factor which influence on learning, of a person does not pay attention towards how to learn a specific knowledge, skill or experience, he can not learn easily bur if the individual pays attention the results are vise versa.
Subject has intelligence and can also pay attention towards learning but he does not have interest in how to learn a specific knowledge, skill or experience, level or process of learning would be very slow.
Mental & physical health:

If knowledge is interesting in nature, any individual can learn it more efficiently.
Recitation is more effective tool of learning, if an individual recite something louder he can learn more effectively.
If the material of knowledge is meaning full, the individual will learn it more effectively and easily, meaning less material nether can be learnt easily nor kept in memory on long term basis.
Exercise & repetition:
Single act is learnt in single trial but complex acts require repeated trails. If a material is difficult to learn it can be learnt through exercises or repeated trials.
By parts learning:
If the material is so long it can be divided into small parts, so individual can learn specific knowledge, skill etc more effectively.
Reward and punishment:
The presence or absence of reward can affect learning, generally, reward is more effective in promoting learning than is punishment, the latter does have some effects on learning, it tends to repress a desired response then to extinguish it.
