Government Engineering College, Modasa has a reputed faculty in the college but it does not have good placement scenario. Silver Oak is also a good college but it is still developing its infrastructure as it is quite new. LDRP Institute of Technology is also a good college with average placement scenario and co-operative faculty. Indus University is also good but has moderate infrastructure.
