I am trying to self-study string theory, beginning with Ibanez and Uranga (String Theory and Particle Physics). Unfortunately, the book contains no problems, so I'm not sure whether I am fully understanding the material.
Are there any pedagogical string theory problem sets, for a beginner, preferably with solutions, available on the web that would accompany my book? I.e. questions initially covering the quantization and symmetries of the Nambu-Goto and Polyakov actions, the wordsheet etc.
